could you help me out with the first and just point me in the right direction for the first i cant seem to get the steps in the right order and then it gets all muddled

thank you

A!

**bobpursley**, Saturday, November 7, 2009 at 10:08amlet u= e^x v=(5x-7)

du/dx=e^x dv/dx= 5

f= uv^-1

f'= u d(v^-1)/dx+ v^-1 du/dx

f'= -uv^-2 dv/dx + v^-1 e^x

so...

f'=-5e^x/(5x-7)^2+ e^x/(5x-7

check that.
