Question

Evaluate the indefinite integral.

integral((3dx)/(xln(2x)))

Integral = ________ +C

Answer 1

\[\int\limits_{}^{}\frac{3 dx}{x \ln(2x)}\]

Answer 2

I'll give you a hint, do a u-substitution with u=ln(2x)

Answer 3

d/dx of ln(2x)=2*1/(2x)=1/x

Answer 4

\[\int\limits_{}^{} \frac{3}{x \ln(x)} dx\]

Answer 5

Your "du" calculation is correct, but the substitution isn't, the integral would change to this. Make sense?
