Ab^-3 = -6
Ab^2 = -18
divide to get rid of the A's and you have
b^-5 = 1/3
b^5 = 3
b = 3^(1/5)
Now use that to get A

I cant get A it keeps being nonreal
Ab^2 = -18
A(3^(1/5))^2 = -18
A(3(2/5)) = -18
A = -18 * 3^(-2/5)
= 18 / 9^(1/5)
= 2 * 9^(4/5)
It would be nice if you showed your work ...
A(3^(1/5))^2 = -18
A(3(2/5)) = -18
A = -18 * 3^(-2/5)
= 18 / 9^(1/5)
= 2 * 9^(4/5)
