I need to find the second derivative of y=x(x1)^1/2. I found the first derivative is 2x1/2(x1)^1/2, if someone could check, but I am miserably stuck on the second derivative.

In google type calc101
When you see list of results click on:
Calc101 com Automatic Calculus,linear Algebra,and Polynomals
When page be open click option derivatives
When that page be open in rectangle type your function and click option DO IT
Type your equtations like that:
x(x1)^0.5
2x1/2(x1)^0.5
You will see first and second derivation stepbystep. 
Thank you so much this definitely helps me double check my work!!
