I'd really appreciate it if somebody could show me the working for this question. Try as I might I can't seem to get the correct answer to come up. The question is as follows:

-------------------------------

By writing the function y = ((2x - 5) / (3x + 2))^0.5 in logarithmic form, show that dy/dx = 19/(2((2x-5)^0.5)((3x + 2)^1.5)

-------------------------------

I've used ^ to mean 'to the power of'.

I've spent a while on this question and I'd really like to understand how it's done, it's annoying me! Please help
