Question

Can someone explain how to simplify this. Has to be in exponent form. (49x^1/2y^-2/3)^1/2

Answer 1

when you have exponentns raised to an exponent, you multiply the exponentss
so \[49^{1/2}x ^{1/4}y ^{-1/3}\]

Answer 2

but 49^1/2 =7 and y^-1/3=1/y^1/3
so (7x^1/4)/y^1/3

Answer 3

\[7x^{1/4}/y ^{1/3}\]

Answer 4

ok?

Answer 5

Thanks makes more sense now. Cudos to you!

Answer 6

how does y^-1/3=1

Answer 7

it does't unless y=1

Answer 8

duh. see it now. thanks.
