Question

write 2 simple sentences on how to change a radical to rational expression, and how to change a rational into a radical expression

Answer 1

To change a radical to a rational expression, rewrite the nth root as a fractional exponent: √[n]{x} = x^{1/n}. To change a rational (fractional) exponent into a radical, interpret x^{m/n} as the nth root of x raised to the mth power: x^{m/n} = (√[n]{x})^m.
