$\frac{x^{- 2} y^{\frac{1}{2}}}{x^{\frac{1}{3}} y^{- 1}}$

Step 1

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

$\frac{y^{\frac{1}{2}}}{x^{\frac{1}{3}} y^{- 1} x^{2}}$

Step 2.1

Move $x^{2}$ .

$\frac{y^{\frac{1}{2}}}{x^{2} x^{\frac{1}{3}} y^{- 1}}$

Step 2.2

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

$\frac{y^{\frac{1}{2}}}{x^{2 + \frac{1}{3}} y^{- 1}}$

Step 2.3

To write $2$ as a fraction with a common denominator, multiply by $\frac{3}{3}$ .

Step 2.4

Combine $2$ and $\frac{3}{3}$ .

$\frac{y^{\frac{1}{2}}}{x^{\frac{2 \cdot 3}{3} + \frac{1}{3}} y^{- 1}}$

Step 2.5

Combine the numerators over the common denominator.

$\frac{y^{\frac{1}{2}}}{x^{\frac{2 \cdot 3 + 1}{3}} y^{- 1}}$

Step 2.6
