Please re-post this (and the other two similarly posted questions).

If this problem is a complex fraction as you say, then
  • Do not try to post it vertically (unless you know enough HTML to have it display properly).
  • Instead, post it horizontally:
    • Put each numerator, "big" and "little", in parentheses (unless it is just a single positive number or variable).
    • Put each denominator, "big" and "little", in parentheses (unless it is just a single positive number or variable).
    • Separate numerators and denominators with "/"
    • For example the complex fraction

      would be posted as
      (1/(x-3)-(2x)/(x^2-9))/((-1)/(x+3)+(x+4)/(x^2-9))
      Note how the only numerator or denominator that is not in parentheses is the "1" (and it would be OK to put it in parentheses, too.)
      Believe it or not, this form is both unambiguous and easier to understand than what you posted. And tutors are more like to respond when the problem is posted clearly.
  • Post it in a proper category.
    • Complex fractions have nothing to do with radicals.
    • Complex fractions a a form of "rational expression" and so they should be posted under Algebra.com's "Polynomial and rational expressions" category.
    • By posting in the correct category you will be more likely to get a tutor to respond. Many tutors only look at the types of problems that they like and/or are good at.
    • By posting in an completely unrelated category, tutors who like and/or are good at complex fractions may never see your problem.
