Step 1.1

Move $y^{5}$ .

$\frac{x^{- 8} (y^{5} y^{- 6})}{x^{- 3}}$

Step 1.2

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

$\frac{x^{- 8} y^{5 - 6}}{x^{- 3}}$

Step 1.3

Subtract $6$ from $5$ .

$\frac{x^{- 8} y^{- 1}}{x^{- 3}}$

Step 2

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

$\frac{y^{- 1}}{x^{- 3} x^{8}}$

Step 3

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

$\frac{1}{x^{- 3} x^{8} y}$

Step 4
