please help!!

Answer 1

you just count how many numbers there are like -7 there is 2 so it would be -7^2 there is 4 5s so it would be 5^4

Explanation:

Answer 2

`-7^2 + 5^4`

Explanation:

Essentially, you are seeing how much of each of the same term there is. Add the amount together, and it will be the exponent.

`(-7) * (-7) = -7^(1 + 1) = -7^2\\5 * 5 * 5 * 5 = 5^(1 + 1 + 1 + 1) = 5^4`

Combine the two terms together into an expression. Note that you cannot combine them.

`-7^2 + 5^4` is your answer.
