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

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

The derivative of the upper limit $u=\sqrt{t}$ with respect to $t$ is $1/(2\sqrt{t})$. This factor is used in the chain rule when differentiating an integral with this variable upper limit.

Conditions: $t > 0$.; The upper limit is defined as $u=\sqrt{t}$.
