Please help me simplify this fraction. Or is it already in its simplest form?

Answer:
1 / x^8
Step-by-step explanation:
We know that a^b / a^c = a^ (b-c)
x^7 / x^ 15 = x^ (7-15) = x^-8
We also that that a^-b = 1/ a^b
x^-8 = 1 / x^8
Answer:
1/(x^8)
Step-by-step explanation:
Simplify by the following steps. To make it easier, I will expand them:
First, expand each of the powers out:
[tex]\frac{x^7}{x^{15} } = \frac{x* x * x * x * x * x * x}{x * x * x * x * x * x * x * x * x * x * x * x * x * x * x}[/tex]
When dividing with the same variables with different powers, you are effectively subtracting the powers. Your answer will look like:
[tex]\frac{x^7}{x^(15)} = x^{7 - 15} = x^{-8}[/tex]
Next, simplify. Note that if there is a negative sign in the power, you must change the sign into a positive by flipping the fraction.
[tex]x^{-8} = \frac{1}{x^{8} }[/tex]
1/(x^8) is your answer.
