integral of ln(9sqrt(x))

\int ln (9 x) d x

x (2 ln (3) + \frac{1}{2} ln (x)) - \frac{1}{2} x + C

Solution steps

\int ln (9 x) d x

Apply Integration By Parts

= x ln (9 x) - \int \frac{1}{2} d x

\int \frac{1}{2} d x = \frac{1}{2} x

= x ln (9 x) - \frac{1}{2} x

x ln (9 x) = x (2 ln (3) + \frac{1}{2} ln (x))

= x (2 ln (3) + \frac{1}{2} ln (x)) - \frac{1}{2} x

Add a constant to the solution

= x (2 ln (3) + \frac{1}{2} ln (x)) - \frac{1}{2} x + C

What is the integral of ln(9sqrt(x)) ?
The integral of ln(9sqrt(x)) is x(2ln(3)+1/2 ln(x))-1/2 x+C
