Answer 1

Express 125 = \[5^{x}\] as a logarithmic equation.

Answer 2

\[\large \log_ab=x \iff a^x=b \]
Your problem has:
\[ \large 5^x=125\] try and see if you can write it in logarithmic form.

I guess an easy trick to "visualize" this is pretend that to get the exponential form from the logarithmic form, you look at the base of the logarithm, and the exponent is what's after the equal sign:
