Question

How do you convert radical expressions to fractional exponents?

Answer 1

The reciprocal of the number associated with the radical is the power needed.

Examples:

`root3(5)=5^(1/3)`
`root7(2)=2^(1/7)`

If the radicand (number under the radical sign) has a power in it, the same method still works:

`root4(9^2)=9^(2/4)`

This can be simplified to get `9^(1/2)`.
