Homework Statement
$$\int_{0}^{2} r\sqrt{5-\sqrt{4-r^2}} dr$$
Homework Equations
The Attempt at a Solution
would i substitute ##u=4-r^2##?
After of which I would input into the integral and get:
$$\int_{0}^{2} \sqrt{5-\sqrt{u}}du$$
What would I do here? Do I just work inside the radical(so 5r - 2/3u^3/2)? Or do I have to account that it's inside a radical when solving?
