Question

Choose the correct simplification of x^2/x^7.

A. x^5

B. x^9

C. 1/x^5

D. x^7*y^12/x^4*y^9

Answer 1

Expand it out and then cancel.

Answer 2

\[\dfrac{x \cdot x}{x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x}\]

Answer 3

\(\dfrac{x}{x} = 1\) so cancel out 1 x on the bottom for every x on the top.
