15624=x\times \frac{1-15625}{1-5}
Calculate 5 to the power of 6 and get 15625.
15624=x\times \frac{-15624}{1-5}
Subtract 15625 from 1 to get -15624.
15624=x\times \frac{-15624}{-4}
Subtract 5 from 1 to get -4.
15624=x\times 3906
Divide -15624 by -4 to get 3906.
x\times 3906=15624
Swap sides so that all variable terms are on the left hand side.
x=\frac{15624}{3906}
Divide both sides by 3906.
x=4
Divide 15624 by 3906 to get 4.
