$\frac{8^{- 2} x^{- 3} y^{11}}{x^{2} y^{- 5}}$

Step 1

Move $8^{- 2}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{x^{- 3} y^{11}}{x^{2} y^{- 5} \cdot 8^{2}}$

Step 2

Move $x^{- 3}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{y^{11}}{x^{2} y^{- 5} \cdot 8^{2} x^{3}}$

Step 3

Multiply $x^{2}$ by $x^{3}$ by adding the exponents.
