Integral of √x

∫x dx=23x32+C\int \sqrt{x}\,dx = \frac{2}{3}x^{\frac{3}{2}} + C

Rewrite as x^(1/2) and apply the power rule: add one to the exponent, divide by the new exponent.

Step by step

  1. Power rule

    ∫uⁿ du = uⁿ⁺¹/(n+1).

    ∫x dx=23x32\int \sqrt{x}\,dx = \frac{2}{3}x^{\frac{3}{2}}
0.511.522.533.544.550.511.522.5
  • f(x) = √x
  • F(x) + C

Every choice of C gives a valid antiderivative, since shifting up or down doesn’t change the slope.

How do you integrate √x?

Rewrite as x^(1/2) and apply the power rule: add one to the exponent, divide by the new exponent.

How can I check the answer?

Differentiate it: the derivative of 23x32\frac{2}{3}x^{\frac{3}{2}} is x\sqrt{x}. CalcViz checks every antiderivative this way before showing it.
