I think I did these correctly but before I do anymore of the same problems I was wondering if you guys could check them for me
Simplify with no radicals or negative exponents:
1. (x(squareroot 16xt^2))^2
I'm not certain what sign to use on the keyboard for squareroot symbo
Well this is what I did.
(x^2)(16xt^2)
16x^3t^2
2. (3ab)^-1(a^2b^-1)^2
(a^2)(b^-2) / (3ab)
a^2 / 3ab^3
a / 3b^3
Any help or advice would be great
