integral of (ln(4x))^2

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

x ln^{2} (4 x) - 2 (x ln (4 x) - x) + C

Solution steps

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

Apply Integration By Parts

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

\int 2 ln (4 x) d x = 2 (x ln (4 x) - x)

= x ln^{2} (4 x) - 2 (x ln (4 x) - x)

Add a constant to the solution

= x ln^{2} (4 x) - 2 (x ln (4 x) - x) + C
