Anybody good at maths?

@dumpstermeow A squared + b squared = c Squared

@xxxxxx I’m not sure.
I know so far the that natural logs are with e.
But I think it’s qite simple the rearrangement. Just not sure he w to do it. You maybe right regarding the correct term for the In.
I think it’s equivalent to 7x but n T sure how they get to it.
Or rather can this be done in the calculator and if so whcit’s h buttons do I press?

@xxxxxx yes it’s the natural logarithm which I learnt today 😊 after embarrassing myself with this question.
Now you can see how much I actually don’t know.
Hence the question for help.
😂

@fazer1k I think in terms of the unit I am doing on functions it is the reverse. For example y=x
The Inverse of the function of f(x) = f^-1(x)
And there is an exponential law which describes what to do above. I will have to post a picture of the rule.
I have at least ten of more expressions similar to the above that I need to rearrange.
I will post some stuff tomorrow
