Very stupid question, I know :)

A powered by B equals C. If I know A and B, it's easy to compute C

If I know A and C, it's also not so hard just by using logarithms

But what if I have B and C, how to get A?

If you could give an example is some JS, C or Python, that would really help me understand things.

Thank you so much!

if $x^2=4$, then $x= \sqrt 4$ – Mauro ALLEGRANZA Oct 11 '21 at 12:51

If $a,b>0$, then $a^b=e^{b \ln a}$. – nicomezi Oct 11 '21 at 12:59

In python it would be something like A = C ** (1 / B) – AlexSp3 Oct 11 '21 at 13:01
Of course, ‍♂️, thank you :) – shal Oct 11 '21 at 16:20
