Hi, I have no idea how to solve and would appreciate if you can guide me step by step. So this what I need help rationalizing : (x—9) / (√x +3) ...

Rationalize the denominator. The variable represents a positive real number. (cube root of 24t^3)/ (cube root 108t^2)

Rationalize the denominator. (Simplify your answer completely.) ((square root of 6) + (square root of 5)) / ((square root of 6) - (square root of 5))

This is for my trig class. Thanks for the help!
