    \[(4+\sqrt{27})/(2-\sqrt{27})\] multiply top and bottom by (2 + root27), then foil. this gives you a numerator of 8+6root27+27 and a denominator of 4-27, which simplifies to a numerator of 35+6root27 over -23, which again simplifies to 35+18root3, all over -23

    your numerator is correct but needs to be simplified. your denominator is wrong - it should be 4-9*27, which is 4-81, which is -77

    i know, it means its 4 minus 9times27

    okay so hold on after i foil my number would simplify to 89+14root27. my denonimator would be 4-9*27?

    not number, i meant numerator.

    yes, and then that denominator is -77, and the numerator can be simplified further: root27 is 3root3, so 14root27 is 14*3root3 which is 42root3

    oooooh i get it. so would 89+42root3 over -77 the answer or do i simpify even more?
