Answer 1

The answer is A)1/7^32. Hope this helps <333

Answer 2

The answer is A. (From Edge 2020)

Add the exponents in (7^5) and (7^3)

7^5 + 3 = 7^8

Now we have (7^8)^-4.

Use the reciprocal of 7^8‬. The reciprocal is
`(1)/(7^8)`.

We now have
`((1)/(7^8))^4` . Multiply the exponents.

`((1)/(7^8))^4` = 1/7^8 × 4 = 1/7^32
