Is the cube root of 3 rational
WitrynaThe situation is different with cube roots. Every number has exactly one cube root. The cube root of a positive number is positive, and the cube root of a negative number is negative. Just as with square roots, some cube roots are irrational numbers and some are not. Cube roots are treated the same as square roots in the order of operations. WitrynaRadicals with Rational Exponent: There are some proper rules that deal with radical terms or radical expressions. These rules are necessary when converting a radical expression into an expression that contains a radical or fractional exponent. The rules are: n√x = x1 n x n = x 1 n. n√xm =x m n x m n = x m n.
