Using one application of integration by parts:
Integral[log[10]x] dx
=xlog[10]x-x+C

This would work if the logarithm was to the base e.

And Drongoski, I know of Salman Khan - I follow him pretty often actually, see whats updated/where he's done talks.

But people from India, Pakistan, Bangladesh & Sri Lanka are referred to as South Asians.

I remember that guy. He is also Salman Khan?

If you already know integration by parts in year 10, what were you bellyaching about doing MX1? By Yr 11 you'd be capable of sitting the MX1 & MX2 exams. You'll get ATAR of 99.99.

Agreed. You're already much further ahead than some Year 12 students.

isnt the derivative of log[10]x=1/(xln(10)
Yes, it is. However remember you're integrating , there's no need to differentiate that function.
