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

Step 1

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

$\frac{1}{a^{2} a^{- \frac{1}{2}}}$

Step 2

Multiply $a^{2}$ by $a^{- \frac{1}{2}}$ by adding the exponents.

Step 2.1

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

$\frac{1}{a^{2 - \frac{1}{2}}}$

Step 2.2

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

$\frac{1}{a^{2 \cdot \frac{2}{2} - \frac{1}{2}}}$

Step 2.3

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

$\frac{1}{a^{\frac{2 \cdot 2}{2} - \frac{1}{2}}}$

Step 2.4

Combine the numerators over the common denominator.

$\frac{1}{a^{\frac{2 \cdot 2 - 1}{2}}}$

Step 2.5

Simplify the numerator.
