integral of xsqrt(x^2+5)

\int x x^{2} + 5 d x

\frac{1}{3} (x^{2} + 5)^{\frac{3}{2}} + C

Solution steps

\int x x^{2} + 5 d x

Apply u-substitution

: \int u^{2} d u

= \int u^{2} d u

Apply the Power Rule

: \frac{u ^{3}}{3}

= \frac{u ^{3}}{3}

Substitute back

u = x^{2} + 5

= \frac{( x ^{2} + 5 ) ^{3}}{3}

Simplify

\frac{( x ^{2} + 5 ) ^{3}}{3} : \frac{1}{3} (x^{2} + 5)^{\frac{3}{2}}

= \frac{1}{3} (x^{2} + 5)^{\frac{3}{2}}

Add a constant to the solution

= \frac{1}{3} (x^{2} + 5)^{\frac{3}{2}} + C

\int (- x + 3)^{2} d x

(ln (ln (x)))^{^{'}}

f (x) = x^{3} (3 - x)^{2}

y = cot^{2} (sin (x))

\frac{\partial}{\partial x} ((\frac{e}{y})^{x})
