Homework Statement
Differentiate.
f(x) = (x) (square root of (x2+5))
Homework Equations
The Attempt at a Solution
f(x) = (x) (square root of (x2+5))
=(x)(x2+5)1/2
f'(x)=(x)1/2(x2+5)-1/2(2x)+(1)(x2+5)
=x3/(x2+5)1/2+(x2+5)1/2
I'm having problems simplifying. The answer in the back of the book is 2x^2 + 5 / Square root of x^2+5..
