Step 1: Recall the definition of a square root in terms of exponents.
The square root of a number $a$ can be written as $a$ raised to the power of $\frac{1}{2}$.
Step 2: Express $\sqrt{a}$ using fractional exponents.
$$ \sqrt{a} = a^{\frac{1}{2}} $$
Step 3: Compare this result with the given options.
The options are:
[A] $a^{\frac{1}{2}}$
[B] $a^{-2}$
[C] $a^{2}$
[D] $a^{-\frac{1}{2}}$
The expression $a^{\frac{1}{2}}$ matches option [A].
The final answer is $\boxed{\text{A}}$.
