Solve y=xxxx

$$y=xxxx$$

Solve for y

$$y=x^{4}$$

Solution Steps

Multiply x and x to get x^{2}.

$$y=x^{2}xx$$

To multiply powers of the same base, add their exponents. Add 2 and 1 to get 3.

$$y=x^{3}x$$

To multiply powers of the same base, add their exponents. Add 3 and 1 to get 4.

$$y=x^{4}$$

Solve for x (complex solution)

$$x=i\sqrt[4]{y}$$

$$x=\sqrt[4]{y}$$

$$x=-\sqrt[4]{y}$$

$$x=-i\sqrt[4]{y}$$

Solve for x

$$x=\sqrt[4]{y}$$

$$x=-\sqrt[4]{y}\text{, }y\geq 0$$
