e^{5x}=10
Use the rules of exponents and logarithms to solve the equation.
\log(e^{5x})=\log(10)
Take the logarithm of both sides of the equation.
5x\log(e)=\log(10)
The logarithm of a number raised to a power is the power times the logarithm of the number.
5x=\frac{\log(10)}{\log(e)}
Divide both sides by \log(e).
5x=\log_{e}\left(10\right)
By the change-of-base formula \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
x=\frac{\ln(10)}{5}
Divide both sides by 5.
