9^{12}=9^{x}
To divide powers of the same base, subtract the denominator's exponent from the numerator's exponent. Subtract 11 from 23 to get 12.
282429536481=9^{x}
Calculate 9 to the power of 12 and get 282429536481.
9^{x}=282429536481
Swap sides so that all variable terms are on the left hand side.
\log(9^{x})=\log(282429536481)
Take the logarithm of both sides of the equation.
x\log(9)=\log(282429536481)
The logarithm of a number raised to a power is the power times the logarithm of the number.
x=\frac{\log(282429536481)}{\log(9)}
Divide both sides by \log(9).
x=\log_{9}\left(282429536481\right)
By the change-of-base formula \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
