2^{x}=\frac{1}{32}
Use the rules of exponents and logarithms to solve the equation.
\log(2^{x})=\log(\frac{1}{32})
Take the logarithm of both sides of the equation.
x\log(2)=\log(\frac{1}{32})
The logarithm of a number raised to a power is the power times the logarithm of the number.
x=\frac{\log(\frac{1}{32})}{\log(2)}
Divide both sides by \log(2).
x=\log_{2}\left(\frac{1}{32}\right)
By the change-of-base formula \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
