Question

Simplify (x^-4) over (x^-2). I know this is really simple I just don't know how to go about solving it >.<

Answer 1

@freckles

Answer 2

\[\frac{x^{a}}{x^{b}}=x^{a-b} \text{ by quotient rule }\]

Answer 3

you have the same base
so your answer will be that base to the power of (top exponent - bottom exponent )

Answer 4

So, x^-2?

Answer 5

-4-(-2)
-4+2
-2
the exponent is -2
good job! :)

Answer 6

and from previous thread you can rewrite without negative exponent by doing,,

Answer 7

Ahh, I love you! Thanks a bunch

Answer 8

\[x^{-a}=\frac{1}{x^{a}}\]

Answer 9

np

Answer 10

Exactly what I was going to do ;)

Answer 11

great stuff!
