Pre-Algebra Examples

$- \sqrt[4]{\frac{16}{x^{4}}}$

Step 1

Rewrite $16$ as $2^{4}$ .

$- \sqrt[4]{\frac{2^{4}}{x^{4}}}$

Step 2

Rewrite $\frac{2^{4}}{x^{4}}$ as ${(\frac{2}{x})}^{4}$ .

$- \sqrt[4]{{(\frac{2}{x})}^{4}}$

Step 3

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

$- \frac{2}{x}$
