f' = lim (h>0) [ (c)  (c) ] /h
= lim (h>0) 0/h
= lim (h>0) 0
f' = 0 <<< answer

You know how in the numerator of the derivative expression you see f(x)f(c)? Or f(x+h)f(x) depending on which definition you learned? Well...... What is f of any number you could ever plug in?

From lenpol7: f(x) = Cx^0
Remember x^0 = 1
Hence

f(x) = Cx^0
Remember x^0 = 1
Hence
f'(x) = 0(C)x^(01)
f'(x) = 0 Because anything multiplied by zero (0) = zero(0) .
