integral of sqrt(\sqrt{2)x+1}

\int 2 x + 1 d x

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

Solution steps

\int 2 x + 1 d x

Apply u-substitution

: \int \frac{u}{2} d u

= \int \frac{u}{2} d u

Simplify

\frac{u}{2} : \frac{u}{2}

= \int \frac{u}{2} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= \frac{1}{2} \cdot \int u d u

Apply the Power Rule

: \frac{2}{3} u^{\frac{3}{2}}

= \frac{1}{2} \cdot \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = 2 x + 1

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

Simplify

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

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

Add a constant to the solution

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

(8 x^{3} + 2 x^{2})^{4}

\int_{- 4}^{4} 16 - x^{2} d x

\frac{d y}{d x} = 5 y

21 x y^{^{'}} - ln (x^{7}) = 0

\int \frac{2 x}{( x ^{2} + 5 ) ln ( x ^{2} + 5 )} d x
