Please Help! I'm stuck!

Answer:
C. [tex]5 (\frac{x}{z}) ^1^0[/tex]
Step-by-step explanation:
Hey there!
Given
[tex]\frac{15 x^-^3 z^5}{3 x^7 z ^-^5}[/tex]
Well to solve this we first need to do 15 ÷ 3
= 5
When dividing exponents we actually subtract.
-3 - 7 = -10
5 - -5 = 10
[tex]5 x^-^1^0 z^1^0[/tex]
Hope this helps :)
Answer:
D. 5 (z/x)^10.
Step-by-step explanation:
15/3 = 5
x^-3 / x^7 = x^-10 = 1/x^10
z^5 / z^-5 = z ^10
So the answer is 5 * z^10 * 1/x^10
= 5 z^10 / x^10
= 5 (z/x)^10.
