Solve for X X^4=2

$X^{4} = 2$

Take the 4th root of both sides of the equation to eliminate the exponent on the left side.

$X = \pm \sqrt[4]{2}$

The complete solution is the result of both the positive and negative portions of the solution.

First, use the positive value of the $\pm$ to find the first solution.

$X = \sqrt[4]{2}$

Next, use the negative value of the $\pm$ to find the second solution.

$X = - \sqrt[4]{2}$

The complete solution is the result of both the positive and negative portions of the solution.

$X = \sqrt[4]{2}, - \sqrt[4]{2}$

The result can be shown in multiple forms.

Exact Form:

$X = \sqrt[4]{2}, - \sqrt[4]{2}$

Decimal Form:

$X = 1.18920711 \dots, - 1.18920711 \dots$
