The antiderivative of x\sqrt{x} is 23x3/2\frac{2}{3}x^{3/2}. This is found by rewriting x\sqrt{x} as x1/2x^{1/2} and applying the power rule for integration, which states that ∫xndx=xn+1n+1\int x^n dx = \frac{x^{n+1}}{n+1} for n≠−1n \neq -1.

Conditions: The function is x\sqrt{x}.; The power rule for integration is applied.; The exponent n=1/2n = 1/2.
