x + 2*\/ x 
2x+x2 \sqrt{x} + x
x + 2*sqrt(x)
Detail solution
  1. Differentiate 2x+x2 \sqrt{x} + x term by term:

    1. Apply the power rule: xx goes to 11

    2. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Apply the power rule: x\sqrt{x} goes to 12x\frac{1}{2 \sqrt{x}}

      So, the result is: 1x\frac{1}{\sqrt{x}}

    The result is: 1+1x1 + \frac{1}{\sqrt{x}}


The answer is:

1+1x1 + \frac{1}{\sqrt{x}}
