Question 174540: Rationalize the denominator of the expression. Assume that all variables are postive when they appear.
1. 4/√x+h-√x The answer I have is A. 4(√x+h-√x/h B. 4(√x+h+√x/h or C. 4√x+h+√x/h or D. 4√h/h I choosen D is that correct?
2. √5/√2+3 I have chosen √10+3√5/-7 for my answer is that correct?
3. Simplify the expression : √32x^2y/49 I have choosen 4√2x^2y/7 is that correct or is it 4x√2y/7?
I am stuck.
Can you help me? Thank you
