Simplify the expression.

x^5/x^9

a. 1/x^4

b. x^14

c. 1/x^14

d. x^4

Answer: B. 1/x^4

When you divide the coefficients of exponents you must subtract the exponents. In this cause it got to x^-4. You cannot leave it as a negative exponent so you must put it as the denominator in this cause to get rid of the exponent making the answer b. 1/x^4.
