Simplify x^8 / x^4
A. Because there are 8 factors of x in the numerator and 4 factors of x in the denominator, when the x's cancel you are left with x^4
B. Because the numerator has an exponent of 8 and the denominator has an exponent of 4, when you divide you are left with x^2
C. Because there are 8 factors of x in the numerator and 4 factors of x in the denominator, when the x's cancel you are left with x−^4
D. Because when you are dividing with exponents, you should add the exponents so that you are left with x^12
