## Homework Statement

F(x) = (4/5)*x^(5/4) on the interval of [0,4]

Find the Arc Length

## Homework Equations

Arc Length = Integral (sqrt (1 + [f(x)']^2)) dx

## The Attempt at a Solution

F'(x) = x^(1/4)

Integral from [0,4] of Sqrt (1 + x^(1/2)) dx

I'm not sure where to go with this integral, I'm sure it's a substitution, however I've been at this all day and I have no idea what.
