Answer 1

Answer:D 3^6

Step-by-step explanation:3^8/3^2= 729

Now it is like guess and check which answer equals 729.

1^6=6

3^4=81

3^6=729

Answer 2

D)
`3^6`

Explanation:

Recall the rule
`(x^a)/(x^b)=x^(a-b)` when dividing same bases but they have different exponents

Therefore:

`(3^8)/(3^2)=3^(8-2)=3^6`
