12\times 3^{x-3}=26244
Use the rules of exponents and logarithms to solve the equation.
3^{x-3}=2187
Divide both sides by 12.
\log(3^{x-3})=\log(2187)
Take the logarithm of both sides of the equation.
\left(x-3\right)\log(3)=\log(2187)
The logarithm of a number raised to a power is the power times the logarithm of the number.
x-3=\frac{\log(2187)}{\log(3)}
Divide both sides by \log(3).
x-3=\log_{3}\left(2187\right)
By the change-of-base formula \frac{\log(a)}{\log(b)}=\log_{b}\left(a\right).
x=7-\left(-3\right)
Add 3 to both sides of the equation.
