Logarithmic Functions · Exercise 2

Convert between exponential and logarithmic form.

Remember these logarithmic notations to help complete the following:
Common Logarithm $\text{log}x={\text{log}}_{x}10$
Natural Logarithm $\text{ln}x={\text{log}}_{x}e$

Convert to logarithmic form.
ⓐ $8=2^x$
ⓑ $10^{-2}=0.01$
ⓒ $e^x=40$

Its source prints no answer for this problem, so there's nothing to check against.
