Question 251882: Please help me solve this problem: (squareroot)x^2/18 both the numerator and denominator are under one square root sign.
the instructions say to rationalize the denominator.
Becasue 18's square root is 4.24 I am unsure this is the right answer (x/4.24) I believe I may be missing something. Should I factor out the denominator?

Question 251889: Rationalize the denominator: 2-√(7) divided by √(3) - √(2)
In the examples I have I believe I am supposed to multiply the numberator and denominator by the denominator....is this the correct way to start this equation or am I missing something.
I have read through the lessons and I am still very confused. If someone could show me the steps I would greatly appreciate it as maybe then I could wrap my brain around this.

Question 253687: How would you simplify a problem such as (4t + 7)^2?
I was thinking that what you would do is regroup it by first writing it as (4t-7)* (4t-7)and then from there grouping the two 4ts together and the -7's together; like this (16t)* (49). From there I was thinking that you would then try and get t by itself so that I could solve for it and that to do that I would need to divide 16 from both sides so that the resulting answer would be something like t(49/16). Would that be right?
