integral of 18sqrt(x)

\int 18 x d x

12 x^{\frac{3}{2}} + C

Solution steps

\int 18 x d x

Take the constant out:

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

= 18 \cdot \int x d x

Apply the Power Rule

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

= 18 \cdot \frac{2}{3} x^{\frac{3}{2}}

Simplify

18 \cdot \frac{2}{3} x^{\frac{3}{2}} : 12 x^{\frac{3}{2}}

= 12 x^{\frac{3}{2}}

Add a constant to the solution

= 12 x^{\frac{3}{2}} + C

\int e^{2 x} arctan (e^{x} - 1) d x

\int sin^{2} (x) tan (x) d x

\int \frac{1}{x ^{2} - 8 x + 25} d x

x^{- 2}

\int \frac{e ^{2 x}}{( e ^{x} + 1 ) ^{2}} d x
