Help with this plzzzzzzzzzzzzzz

Answer 1

Answer:
`4^0`

Explanation:

`4^5*4^-^7/4^-^2`

Rewriting this;

`(4^5*4^-^7)/(4^-^2)`

When you multiply by the same base, you add exponents.

`(4^5^+^(^-^7^))/(4^-^2)`

`(4^5^-^7)/(4^-^2)`

`(4^-^2)/(4^-^2)`

When you divide by the same base, you subtract exponents.

`4^-^2^-^(^-^2^)`

`4^-^2^+^2\\4^0`
