# Algebra and General Mathematics: Radicals

(Last Updated On: February 5, 2020)

A radical is an expression of the form n√x which denotes the principal nth root of x.

n√x = x(1/n)

where:

n – index

in terms of fractional exponent:

n√xm = (n√x)m = xm/n

1. n√xm = (n√x)m
2. n√x ·n√y = n√(xy)
3. (n√x) / (n√y) = n√(x/y), y ≠ 0
4. m√(n√x) = mn√x
5. (n√x)n = x
6. (n√xn) = | x |, (n = even)               (n√xn) = x, (n = odd)
