The expression \( 5 - \sqrt{3} \) can be rewritten using a rational exponent. The square root, \( \sqrt{3} \), can be expressed as \( 3^{1/2} \).
However, if you want to express the entire expression \( 5 - \sqrt{3} \) as a rational exponent, we typically just focus on \( \sqrt{3} \) specifically. The rational exponent for \( \sqrt{3} \) is:
\[ \frac{1}{2} \]
If we are asked for the rational exponent related to just \( \sqrt{3} \), the answer is:
The rational exponent is \( \frac{1}{2} \).
