Answer:

Step-by-step explanation:

<h2><u>QUESTION 9: </u></h2>

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.

<h2><u>QUESTION 10:</u></h2>

Substitute the 5 into where x is.

This gives you the equation 5^{2}-5.

5^{3} is 125

125-5 gives you 120.

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
