Question 152752: Solve for all values of x: square root sign (x+7) - square root sign (x+2)=1
I am not sure what to do with this question. I think maybe I should mutilply by x+7 and x+5 to remove the square root sign, but then I am lost
Thanks

Question 154073: I was trying to solve this problem, I tried rationalizing the denominator but I could not eliminate the middle terms in the denominator because the exponents of the variable inside the cube root sign is not the same. I took this problem from the College Algebra book by William Hart, 4th Edition. This is under exercise 53, problem number 148, page 127. This is the problem:

If only the index of the radicals in the denominator is equal to 2,and not a 3 (which is a cube root) I could immediately perform rationalization.
I hope somebody could help me.
thanks and best regards,
jomar
