Stuart the ExamSolutions GuyOctober 24, 2016 at 10:18 pmNo as you are taking away 1 root 3 from 7 root 3

edJanuary 1, 2017 at 12:37 pmfor the first simplify question I got 8root8 why is that wrong?

Stuart the ExamSolutions GuyJanuary 1, 2017 at 5:06 pm8root(8) is correct but not fully simplified. root(8) = root [(4)(2)] = root(4) root(2) = 2 root(2)

So 8 root(8) = 8 x 2 root(2) = 16 root(2)
