Step 1.1

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

$\frac{x^{- 4 - 6} y^{2}}{y^{6}}$

Step 1.2

Subtract $6$ from $- 4$ .

$\frac{x^{- 10} y^{2}}{y^{6}}$

Step 2

Move $x^{- 10}$ to the denominator using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$\frac{y^{2}}{y^{6} x^{10}}$

Step 3
