integral from 1 to e of ln(15x)

\int_{1}^{e} ln (15 x) d x

e ln (15 e) - e - ln (15) + 1

Decimal

5.65319 \dots

Solution steps

\int_{1}^{e} ln (15 x) d x

Apply Integration By Parts

= [x ln (15 x) - \int 1 d x]_{1}^{e}

\int 1 d x = x

= [x ln (15 x) - x]_{1}^{e}

Compute the boundaries:

e ln (15 e) - e - ln (15) + 1

= e ln (15 e) - e - ln (15) + 1
