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

Step 1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

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

Step 2

Apply the rule $x^{\frac{m}{n}} = \sqrt[n]{x^{m}}$ to rewrite the exponentiation as a radical.

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

Step 3

Anything raised to $1$ is the base itself.

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