Question

Simplify (y^10/125y^-5)^-2/3

Answer 1

\[( y^{10} / 125y^{-5} )^{-2/3} = y^{10(-2/3)}/125y^{-5(-2/3)}\]

Answer 2

what do you do after that?

Answer 3

simplify the 10(-2/3) and -5(-2/3) so you'l be left with \[y^{-20/3}/125y^{10/3}\]

Answer 4

and then move the y in the denominator to the numerator by switching the sign of its exponent

Answer 5

From denominator or the numerator? I thought you move the numerator

Answer 6

because the numerator is the one that has the negative sign

Answer 7

You can move both, but yes to make the answer contain only positive exponents you can move the numerator down

Answer 8

so the answer will be 1/125y^30/3

Answer 9

yes but dont forget to simplify the 30/3

Answer 10

1/125y^10

Answer 11

yay :)

Answer 12

whoo thanks!
