Solve for x x^7=128

$x^{7} = 128$

Take the 7th root of both sides of the equation to eliminate the exponent on the left side.

$x = \sqrt[7]{128}$

Simplify $\sqrt[7]{128}$ .

Rewrite $128$ as $2^{7}$ .

$x = \sqrt[7]{2^{7}}$

Pull terms out from under the radical, assuming real numbers.

$x = 2$
