integral of (2log_{4}(x))/x

\int \frac{2 lo g _{4} ( x )}{x} d x

2 (lo g_{4} (x) ln ∣ x ∣ - \frac{ln ∣ x ∣ ^{2}}{4 ln ( 2 )}) + C

Solution steps

\int \frac{2 lo g _{4} ( x )}{x} d x

Take the constant out:

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

= 2 \cdot \int \frac{lo g _{4} ( x )}{x} d x

Apply Integration By Parts

= 2 (lo g_{4} (x) ln ∣ x ∣ - \int \frac{ln ∣ x ∣}{2 ln ( 2 ) x} d x)

\int \frac{ln ∣ x ∣}{2 ln ( 2 ) x} d x = \frac{ln ∣ x ∣ ^{2}}{4 ln ( 2 )}

= 2 (lo g_{4} (x) ln ∣ x ∣ - \frac{ln ∣ x ∣ ^{2}}{4 ln ( 2 )})

Add a constant to the solution

= 2 (lo g_{4} (x) ln ∣ x ∣ - \frac{ln ∣ x ∣ ^{2}}{4 ln ( 2 )}) + C

\int \frac{1}{x - 100} d x

\int \frac{1}{x ^{3} ( x ^{4} + 1 )} d x

\int 1 + 4 x^{2} (x^{2} - 1) d x

\int \frac{e ^{6 x} + 2}{e ^{6 x} + e ^{- 6 x}} d x

\int e^{8} d x
