Answer 1

ur answer of this question is 225

Answer 2

$\huge\mathcal{Answer:}$

$( \frac{1}{3} ) ^{ - 2} \times (\frac{1}{5} ) ^{ - 2}$

Here,the power is negative So we have to reciprocal the base to get a positive power

$(3 )^{2} \times ( {5})^{2}$

Powers are equal so let's take it common

$(3 \times 5) ^{2}$

$({15})^{2}$

$15 \times 15$

$225$
