I need help with this question. The directions say to evaluate and express the answer in the simplest form.

Step-by-step explanation:

(9)^-5/2

In order to get rid of the negative exponent, take the reprocal of 9/1

⇒()^5/2

⇒This is also the same thing but we’re are breaking it down.

⇒We are further breaking this down...

^ is technically the square root of a number.

=1

=243

I’m only 8 years old ;-;

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
