Logarithmus Ln Log richtig rechnen Casio fx991 DE CW

Hi guys, today in electro-training 5 in 100, Casio FX991DECW and today we take a look at the logarithm. So I want to calculate a logarithm to the base 2 of 5 and for that I need this button here on the side. When I press it, I get a logarithm that I can assemble myself, so base 2 I said, of 5. I press the cursor key to the right and enter and I have my corresponding solution here. But it can sometimes be that I need the 10th logarithm, because it is often known and the 10th logarithm is hidden here under the square key. Simply shift and then press the square key, then I have the 10th logarithm, so log of 10 should hopefully be 1. And yes, there is often the case that you need a natural logarithm, the logarithm naturalis, which is hidden here under the log key. To do this, I need shift and then the log key and yes, if I calculate the log of 2, I should get 0.69, which is still good. So mathematics is not transient, I have to say, always a nice thing. Yes, I hope you enjoyed this short video about calculating logarithms. If so, give it a thumbs up, up here you can subscribe, here you can watch another cool new video. Take care, bye and see you soon!
