Answer:

Explanation:

Hi Ashley, this looks harder than it really is :)

recall your powers rules

so
x^(2) *
x^(2) =
x^(2+2)=
x^(4)

knowing that you can probably figure this out. But I'll help anyway


x^(?+3) = 1 /
x^(2)

now flip over the fraction to make this even easier


x^(?+3) =
x^(-2)

ohhhh I bet you can see it now, huh

we just need 3 plus something to equal -2

that's negative 5 , right???


x^(-5+3) =
x^(-2)

ahh, nice , now just break it back up


x^(-5) *
x^(3) = 1 /
x^(2)

got it???

Explanation:

x^y × x^3 = 1/(x^2) = x^(-2)

that means

y + 3 = -2

y = -5

the missing exponent is -5

x^(-5) × x^3 = 1/(x^2)
