Math Help - Find

1. Find

No words can explain where i am at on this problem
find f'(x)

a) f(x) = log(1/2) x
the 1/2 is subscript

2. Consider that the function you have is simply Log[x]/Log[1/2] = -Log[x]/Log[2], where the logs here are in base e.... then differentiate normally since -1/Log[2] is just a constant! Should get -1/Log[2] * 1/x
