Question

How do you write `m^2.4` in radical form?

Answer 1

`m^2.4 = m^(12/5) = root(5)(M^12)`

Explanation:

Rational exponent, like `m^(P/Q)` mean, by definition, `root(Q)(m^P)`

Therefore,
`m^2.4 = m^(12/5) = root(5)(M^12)`

The reason for the above definition of rational exponent can be found in the lecture found at menu items "Algebra" - "Exponential Functions" on UNIZOR.COM
