integral of 4e^xsqrt(8+e^x)

\int 4 e^{x} 8 + e^{x} d x

\frac{8}{3} (8 + e^{x})^{\frac{3}{2}} + C

Solution steps

\int 4 e^{x} 8 + e^{x} d x

Take the constant out:

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

= 4 \cdot \int e^{x} 8 + e^{x} d x

Apply u-substitution

: \int u d u

= 4 \cdot \int u d u

Apply the Power Rule

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

= 4 \cdot \frac{2}{3} u^{\frac{3}{2}}

Substitute back

u = 8 + e^{x}

= 4 \cdot \frac{2}{3} (8 + e^{x})^{\frac{3}{2}}

Simplify

4 \cdot \frac{2}{3} (8 + e^{x})^{\frac{3}{2}} : \frac{8}{3} (8 + e^{x})^{\frac{3}{2}}

= \frac{8}{3} (8 + e^{x})^{\frac{3}{2}}

Add a constant to the solution

= \frac{8}{3} (8 + e^{x})^{\frac{3}{2}} + C

x \to 6 lim (x + 3)

(arctan (e^{x}))^{^{'}}

\frac{d}{d x} (arccsc (2 x + 1))

\int (sin (x))^{3} (cos (x)) d x

x \to - 1 lim (\frac{1}{x + 1})
