The 32 is 2 5, so this will come out of the radical. The x 10 = (x 2) 5, so an x 2 will come out. The y 6 = (y 5)(y 1), so I'll be able to pull a y out, while leaving the last y inside the radical.
Web"Roots" (or "radicals") are the "opposite" operation of applying exponents; we can "undo" a power with a radical, and we can "undo" a radical with a power. For instance, if we square 2, we get 4, and if we "take the square root of 4 ", we get 2; if we square 3, we get 9, and if we "take the square root of 9 ", we get 3. Webmore. The thing about a square root of a fraction is that: sqrt (35/9) = sqrt (35)/sqrt (9) in other words, the square root of the entire fraction is the same as the square root of the numerator divided by the square root of the denominator. With that in mind, we can simplify the fraction: sqrt (35)/3.
