the 4th root of 49 is the square root of the square root of 49 since square root 49 =7 then simplify is square root of 7
4th root is same as square root of square root: sqrt(256) = 16, and sqrt(16) = 4
The fourth root of +100 is 3.16228. (rounded)A negative number can't have a real even-numbered root.Technically, the 4th root of -100 is 3.16228 i."i" is ( or "i am") the square root of -1 .
The 4th root of 3,888 is ± 7.896444
There are only three roots given so, in general, there is no unique answer. However, if it is a real polynomial, then its complex roots must come in conjugate pairs. Then 6i is a root implies that -6i is a root. So the polynomial is (x - 4)(x + 3)(x + 6i)(x - 6i) = (x2 - x - 12)(x2 + 36) = x4 + 36x2 - x3 - 36x - 12x2 - 432 = x4 - x3 + 24x2 - 36x - 432
