Find f'(x)

The answer is 3/(2sqrt(3x+15)

Can anyone who does this please explain step by step why you did what you did? I have a lot of difficulty finding the derivative with radicals.

**Quidditch**, Wednesday, May 21, 2008 at 12:30amInstead of radical form, write the problem in exponential form.

f(x)=(3x + 15)^(1/2)

f'(x)=(1/2)((3x+15)^(1/2 - 1)) 3

f'(x)=(3/2)(3x+15)^(-1/2)

f'(x)=3/(2*(3x+15)^(1/2))
