Question

Please help me!!!!!!

Answer 1

Explanation:

QUESTION 9:

First, substitute the 2 into where x is. This gives you
`4^(2)`-10.

`4^(2)` means you need to multiply 4 by itself (4x4), which is 16.

16 - 10 is 6.

QUESTION 10:

Substitute the 5 into where x is.

This gives you the equation
`5^(2)`-5.

`5^(3)` is 125

125-5 gives you 120.

Answer 2

9.

x = 2, we are evaluating the expression 4^x - 10

4^2 - 10

16 - 10

6

10.

x = 5, we are evaluating the expression x^3 - x

5^3 - 5

(5 x 5 x 5) - 5

125 - 5

120

Hope this helps!! :)
