This is fairly simple. You would just substitute the answer choices in for 'n'.
3^-243=0
So, A. isn't correct.
3^-27=1.31137265.....
So, B. isn't correct.
3^-4=0.123456789 In fraction form this is 1/81
So, we think C. is the correct answer, but just to be sure, let's try D.
3^4=81 In fraction form this would be 81/1.
So, C. is our answer.
Hope this helps!!
