$\frac{y^{- 2}}{y}$

Step 1

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

$\frac{1}{y \cdot y^{2}}$

Step 2

Multiply $y$ by $y^{2}$ by adding the exponents.

Step 2.1.1

Raise $y$ to the power of $1$ .

$\frac{1}{y^{1} y^{2}}$

Step 2.1.2

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

$\frac{1}{y^{1 + 2}}$

Step 2.2

Add $1$ and $2$ .
