integral of 3/(sqrt(5x-1))

\int \frac{3}{5 x - 1} d x

\frac{6}{5} 5 x - 1 + C

Solution steps

\int \frac{3}{5 x - 1} d x

Take the constant out:

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

= 3 \cdot \int \frac{1}{5 x - 1} d x

Apply u-substitution

: \int \frac{1}{5 u} d u

= 3 \cdot \int \frac{1}{5 u} d u

Take the constant out:

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

= 3 \cdot \frac{1}{5} \cdot \int \frac{1}{u} d u

Apply the Power Rule

: 2 u^{\frac{1}{2}}

= 3 \cdot \frac{1}{5} \cdot 2 u^{\frac{1}{2}}

Substitute back

u = 5 x - 1

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

Simplify

3 \cdot \frac{1}{5} \cdot 2 (5 x - 1)^{\frac{1}{2}} : \frac{6}{5} 5 x - 1

= \frac{6}{5} 5 x - 1

Add a constant to the solution

= \frac{6}{5} 5 x - 1 + C

\int \frac{4}{3 x ^{4}} d x

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

\int x (sin (2 x)) d x

\int (\frac{ln ( x )}{x}) d x

\int (x^{2} + 1) (2 x - 3) d x
