Question 176126: I need to simplify a square root that contains a fraction. The numerator is itself a fraction. It is one plus the square root of 2 over just 2. That is, the numerator of the fraction within the radical is first 1, then the latter 1 is plus the square root of 2 with a denominator of 2 . Then the denominator of the entire radical is 2. I know that this first fractional radical can be simplified to a radical with the numerator of 2 plus the square root of 2 with a denominator of 4. But I do not know the process whereby the first radical is simplified to the next radical. I would appreciate very much an explanation about how this first radical is simplified to the second radical.

Question 177205: Good day to all of the tuitors here. iam just hopeful that my math homework might be solved by one of them. I actually have a little knowledge about conjugate of radical expressions but i have doubts if my final answer is correct. The problem goes like this....... Simplify the square root of x over 2x+1. Now in my try out of answering this question, my answer is square root of x times 2x-1 over 2x-1. Is that correct? pls help me. I need to know the correct answer or i will have trouble sleeping. Thanks to the tuitors. You guys have overwhelming answers.
