Question

How do you write the expression `m^(-1/2)` in radical form?

Answer 1

`= 1/sqrtm`

Explanation:

There are 2 laws of indices that we can apply:

`x^-m - 1/x^m" " and" "x^(1/2) = sqrtx`

Get rid of the negative index first:

`m^(-1/2) = 1/m^(1/2)`

Write the fractional index as a root:

`= 1/sqrtm`
