Question

Evaluate: x^-6/y^-5 * y^-5/x^-6

Answer 1

please rewrite it clearer ... I don't get it at all ! O_O :(

Answer 2

is it? ...\[\Large \frac{x^{-6}}{y^{-5}}\cdot \frac{y^{-5}}{x^{-6}}\]

Answer 3

yess

Answer 4

ok.. sweet, then this is what we're going to do... Use this formula...

\[\LARGE \frac{a^m}{a^n}=a^{m-n}\]

Answer 5

i can't use that formula because there are two different denominators

Answer 6

i mean two different bases

Answer 7

we have...\[\LARGE \frac{x^{-6}\cdot y^{-5}}{x^{-6}\cdot y^{-5}}=x^{-6-(-6)}\cdot y^{-5-(-5)}\]

Answer 8

from there you get... ??

Answer 9

yes

Answer 10

Nice ;)
