$\frac{2^{2} y^{- 6}}{8^{- 1} z^{0} x^{- 7}}$

Step 1

Move $y^{- 6}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{2^{2}}{8^{- 1} z^{0} x^{- 7} y^{6}}$

Step 2

Move $8^{- 1}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$\frac{2^{2} \cdot 8}{x^{- 7} y^{6}}$

Step 3

Move $x^{- 7}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$\frac{2^{2} \cdot 8 x^{7}}{y^{6}}$

Step 4

Simplify the numerator.
