<h3>Answer:   3^5</h3>

Explanation:

The rule used is \left(\frac{a}{b}\right)^{-c}  = \left(\frac{b}{a}\right)^{c}

That rule says to go from a negative exponent to a positive exponent, we apply the reciprocal of the fraction.

So,

\left(\frac{1}{3}\right)^{-5} = \left(\frac{3}{1}\right)^{5} = 3^5
