Integral of \( \displaystyle \sqrt{x} \)

Problem 4.175 · easy Video

Find \( \displaystyle \int \sqrt{x} \, dx \). (Omit the constant of integration.)

\[ \int \sqrt{x}\, dx \]
integral rewriteStart with the integral of the given function. Rewrite the square root as a fractional exponent.✓ Proved
\[ = \frac{2 x^{\frac{3}{2}}}{3} \]
antiderivativeApply the power rule for integration.✓ Proved

Answer \( \frac{2 x^{\frac{3}{2}}}{3} + C \)

Top: the graph of F = 2x^(3/2)/3. A tangent line slides along it, and its slope is plotted below as it goes, tracing f = sqrt(x).

✓ Nihil obstat Every line of this solution was proved by the computer algebra system SymPy. The answer was also checked a second way, without looking at the solution. Reviewers found nothing wrong with the explanation. How we verify

The full receipt

Line	Status	Checked by	Detail
1	✓ Proved	sympy 1.14.0	line 1 is the problem as stated
2	✓ Proved	sympy 1.14.0	simplify(a - b) reduced to 0
3	✓ Proved	sympy 1.14.0	simplify(a - b) reduced to 0
answer	✓ Proved	sympy 1.14.0	final line against the stated answer: simplify(a - b) reduced to 0
answer, a second way	✓ Proved	sympy 1.14.0	SymPy differentiated the stated antiderivative back to the integrand

Proved: SymPy reduced the difference between the two sides to zero. Checked independently: a separate method, named above, confirmed it. Checked numerically: the two sides agree at every sampled point, which is evidence, not proof. Reviewed: a model or a person read it; that is all a sentence can have. Solution by gemma4:26b, checked 2026-10-03 with SymPy 1.14.0.
