Hướng dẫn giải Rubik 7x7

Hello everyone, let's continue to solve the Rubik's Cube along with the equations that we already know. In this Rubik's Cube case, we solve it like solving the Rubik's Cube 5 and Rubik's Cube 3. Each side of the Rubik's Cube has a fixed center. It's different from the Rubik's Cube 6. In the Rubik's Cube 6, it doesn't have a fixed center like this. Now we start to solve it in yellow, red, green, brown and green. We solve it like this. Some people solve it like this. I will show you how to solve it. We solve it like this. 9 cubes first, 8 cubes, and then solve 3 cubes, 3 cubes, 3 cubes. Finally, we solve it like this. We solve it like solving the Rubik's Cube 6 or Rubik's Cube 5. We solve it like this. Now we start to solve it. We will find the center to solve it. For example, like this. Next, like this. This is the center. Next, like this. In this step, we are careful. We may push 3 cubes away. Like this. There are 2 cubes. There is a center. Where is the center? We solve it like this. Like solving the Rubik's Cube 6, we will find the center like this. This is the center. We push it up. We rotate it. We tilt the cube to be inside. We rotate it down to flip it. We solve it like this. This is the center. There are 2 more centers. Like this. These 2 cubes are solved. The other one is here, push this one up and it will move to the white circle, but it's okay. Let's go somewhere else. Turn around. The white circle doesn't move at all. And now... There. Here too. And the black circle here too. Okay. Uh-huh. Now, it's like 6x6. Let's put the circle here. And we use the formula to multiply. Multiply. Push up. Rotate. Push up. Push this one up. Put it here. Turn around. Go back. So, it's multiply. Multiply. There's another corner. There. I'm just doing this side. If we're used to it, we can do this side. Yeah, like this. But to be consistent, we put it up, then down. There. Now we have a white circle. Put a yellow circle here. We also do this one. Put it here. So, it's enough. Then we put it here. But to put it like this, the white circle will also burn. So, we have to be careful. Step back. The white circle will burn. Now, continue. There's another circle here. There's a circle here. There's two circles. There's a corner. Ah, there are two corners here. You see? Up. Down. It's not the same. The middle here. Here. We use the formula to multiply. We do this. Put it here. We do this. Put it here. There. Do it again. It won't bother the white circle. Ah. In the three circles, this one is solved. OK. Continue in the other three circles. For example, this three circles. There's this circle. It's here. We go straight here. It won't bother the white circle. Let's do this. The white will follow, so we move back a step. Move back a step. Move up again. The white will come back. The yellow will be in the same place. We have a set of these three. These three already have a square. But there is a square in the middle. The square in the middle here. We still have a square here. It's not done yet. We take this square. Put it here. We use the notation Mu. Mu here. Then, we have a square. Mu here. Now, we have a square. We use the notation Mu. Mu here. We can do this one more time. Next. Up. Up again. Down. OK. There is one more here. Here. Up. Down. This move is to make the white move back. The white moves back a step. The white moves back. The yellow is done. White. Yellow. Now, let's solve the red. The red is the same. Now, we solve it like this. Inside first. For example, here. For example, we move this square. Down here. By the notation Mu Tra. We move this square. Mu with green. But Tra with red. Tra. Let's see. OK. We continue. We put the red here. We cut Mu with red. Then, we take the red. Tra here. Mu with red. We have two squares. Here is one. Here is two. Done. Now, we continue to cut Mu 3. Here. We move this square here. And move Tra here. To make no change. Then, we move this square down. Continue. The middle square here. The middle here. Done. Here is one. Done. Here is two. The middle here. Sorry. OK. Now, we can use the notation Mu. Like this. Mu. Mu with this square. We put it here. Then, take this square. Tra here. Mu. We also use the notation Mu like this. Mu with this square. Tra again. Here is one here. OK. Here are two squares. We also use the notation Mu. Mu. Mu with this square. Tra here. Mu. Mu with this square. The middle square here. We also use the notation Mu like this. Tra. Up. Rotate. Mu. Mu with this square. Tra. The corner. Up. Rotate. Down. OK. White. Yellow. Red. Now, green. Done. Green. Mu with this square. Day. Mu with this square. Continue. Ah! We have another slot here. We use this slot. We use this slot instead of this slot because it's small. We have only one. So we replace it with this whole slot. Continue. We use the notation Mu and Tra with these slots. Here. One Mu taken. Put in here. Mu. Tra. Here are seven more slots. I will put these balls on this side It's easy Now I will try to borrow This time it is attractive that I borrow 2 balls I borrow 2 balls These 2 balls 1 green ball and 1 green ball and return by 2 green balls No, borrow 2 green balls Return by 2 green balls Borrow 2 green balls Borrow this ball Return by 2 green balls Borrow and return This orange ball is here Very attractive Borrow 2 green balls Return by 2 green balls Now there are 2 green balls Put it here Sorry I was wrong Borrow this side first Borrow and return There is a ball here Borrow and return No, it's not borrow It's like this Next We use the operation Borrow and return However, we can fill it For example, this side has only 1 ball There are 3 balls on this side We can fill it Similarly There are 3 balls on this side OK Now let's see how to borrow Borrow 2 balls here Put it here Borrow and return Continue There are 3 balls here Borrow and return Borrow Return Borrow Return Borrow Return Borrow Tomorrow we will learn Hand Tomorrow we will learn Hand We also have 5x5 and 6x6 Let's take a look at them We can start with red For example, this is red, green, red, green, red, green For example, number 6 Number 6, red, green And this one, red, green, number 6 Here, green, red, green And the other one can be blue I will explain the red and green I will explain it slowly so you can understand Continue I will put these two over here The same algorithm I will put this one over here And the last red and green over here Where is it? Sorry Can you see it? It's hard to see Next, I will explain the red and yellow The red and yellow I will put this red and yellow over here When we put it over here, we only move this line We should not move both lines The same algorithm And there is a red and yellow at the corner Here, red, yellow The last red and white Can you see it? Next, I will explain the other colors For example, we will use the blue and red I will explain it slowly Blue and red Red and blue There are two of them There are three of them I will put these two over here Red and blue Over here Now, I will explain the other colors The other colors are black and white Black and white This color seems to be water Here it is Black and white Where is it? There is a black and white Black and white Next, I will put the blue and yellow There are two of them The blue and yellow It is just the right combination I put the blue and white I will put the blue and white Next, green and white Green and white Next, white and black White and black Here it is There are only two of them Now, we will use number 7 to process the opposite side of the circuit This is the opposite side of the circuit Now, we will process the front of the circuit We can process the outside or the inside In this case, because it is white, we will process the inside So, R2 is not outside, it is inside U2, R', M2, L', B2 and finally R2 This is the opposite side of the circuit In this case, because it is green, we will process the inside So, R2 is not outside, it is inside We will process the outside Now, we will process the inside In this case, because it is red, we will process the inside We will process the outside In this case, because it is red, we will process the inside Now, we will process the inside This is the opposite side of the circuit This is U1 Thank you for watching and see you in the next video!
