Question

What is 243^1/3 in simplest radical form

Answer 1

`\sqrt[3]{243}`

Explanation:

The formula for fractional exponents is
`x^(m)/(n)=\sqrt[n]{x^m}`. In this case, m = 1 and n = 3; therefore,
`243^(1)/(3)=\sqrt[3]{243^1} =\sqrt[3]{243}` (any number to the first power is the same number; Ex.
`4^1=4`).
