Answer 3

Sorry!! I usually put my work with it but I was in a hurry. Well, I put it in my calculator and got 243. But if you want it step by step, this is how I did it:
\[\frac{ 1 }{ 3^{-5}}\]
I simplified the bottom: 3^-5 = 0.0041152

which gave me the new problem
\[\frac{ 1 }{ 0.0041152 }\]
then I divided the top by the bottom:

\[1\div 0.0041152=243\]

Hope this helps!! Bree :) @whpalmer4 & @anonymous_user
