1.03^{x}=1.5
Use the rules of exponents and logarithms to solve the equation.
\log(1.03^{x})=\log(1.5)
Take the logarithm of both sides of the equation.
x\log(1.03)=\log(1.5)
The logarithm of a number raised to a power is the power times the logarithm of the number.
x=\frac{\log(1.5)}{\log(1.03)}
Divide both sides by \log(1.03).
x=\log_{1.03}\left(1.5\right)
By the change-of-base formula \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
