[tex](3^{-3})(3^{-2})[/tex]b)
[tex](5^{-6})(5^{-3})[/tex]Required:
We need to eveluate both
Explanation:
a)
[tex]\frac{1}{3^3}*\frac{1}{3^2}=\frac{1}{243}[/tex]b)
[tex]\frac{1}{5^6}*\frac{1}{5^3}=\frac{1}{5^9}[/tex]Final answer:
[tex]\begin{gathered} \frac{1}{3^5}=\frac{1}{243} \\ \\ \frac{1}{5^9} \end{gathered}[/tex]
