Answer:
n = 4
Step-by-step explanation:
Add the powers of 3
4 -5 -3 = - 4
Now these make just 1 power that you have to deal with.
3^-4
and that equates to 1/3 ^ n = 3^ -n
So what is the answer?
3^-4 = 3^-n
Since the bases are the same, the powers can be equated.
- 4 = - n
divide by - 1 to get 4 = n
