Step 1.1

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$\sqrt[6]{\frac{1}{w^{- 6 + 4}}}$

Step 1.2

Add $- 6$ and $4$ .

$\sqrt[6]{\frac{1}{w^{- 2}}}$

Step 2

Move $w^{- 2}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$\sqrt[6]{w^{2}}$

Step 3

Rewrite $\sqrt[6]{w^{2}}$ as $\sqrt[3]{\sqrt{w^{2}}}$ .

$\sqrt[3]{\sqrt{w^{2}}}$

Step 4

Pull terms out from under the radical.

$\sqrt[3]{| w |}$
