Answer:


x=\frac{\ln(20)}5


x \approx 0.599

Explanation:

We can solve for
x in the expression:


e^(5x)=20

by taking the natural log of both sides:


\ln(e^(5x)) = \ln(20)

simplifying the left side


5x = \ln(20)

dividing both sides by 5


\boxed{x=\frac{\ln(20)}5 \approx 0.599}

Further Note

The natural log function returns the exponent that the mathematical constant
e must be raised to so that the resulting value is the number being operating on.

For example:


\ln(e^2) = 2

because
e to the power of
2 results in
e^2.
