The Negative Exponent Rule states that \( a^{-n} = \frac{1}{a^n} \). To use this rule, we can express the exponent \( \frac{1}{2} \) in a way that involves a negative exponent.
We know that:
\[ 3^{1/2} = \frac{1}{3^{-1/2}} \]
So, an equivalent expression to \( 3^{1/2} \) using a negative exponent is:
\[ \frac{1}{3^{-1/2}} \]
Thus, \( 3^{1/2} \) can be rewritten as \( \frac{1}{3^{-1/2}} \).
