What is 3⁴ x 3-⁵ x 3-² = ⅓ ⁿ

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

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
