8=x\times 4^{2}+4
Add 2 and 2 to get 4.
8=x\times 16+4
Calculate 4 to the power of 2 and get 16.
x\times 16+4=8
Swap sides so that all variable terms are on the left hand side.
x\times 16=8-4
Subtract 4 from both sides.
x\times 16=4
Subtract 4 from 8 to get 4.
x=\frac{4}{16}
Divide both sides by 16.
x=\frac{1}{4}
Reduce the fraction \frac{4}{16} to lowest terms by extracting and canceling out 4.
