Thread: Derivatives involving logarithms

How do I find the derivative of this function?

My main concern is with the logarithms, can i bring the 6 infront of logbase5 x?

If you can solve it all, that would be nice.

The problem becomes
x^2 + 6ln(x)/ln(5) + ln(sinx)/ln(7), where ln(x) is the log of x to the base e..
ln(5) and ln(7) are constants.
