Question

(b^-2/3)^9/2 I'm stumped on this problem. I'm simplifying by the laws of exponents and I can't have any negative exponents. I've got to this point and I'm not sure what to do next (b^-2/3)^9/2=(1/b^2/3)^9/2 any advice?

Answer 1

you get b^(-3) = 1/b^3

Answer 2

first is b^(-18/6)

Answer 3

because (x^a)^b = x^(a*b)

Answer 4

yes this is ok

Answer 6

so than you get -18/6 like exponent what equal -3

Answer 7
