200^600=200^(2*300)=400^300
????
200^600=(200^2)^300=400^300????

There are 1200 respondents to a poll,each favoring their preference for candidates A,B and C,54% favored A,48% favored B,and 42% favored C,and there is 30% favored both A and B,what's largest possible number respondants favoring C,but not C&B,norC&A??
----------------------------
my An :
P(A)= 648
P(B)= 576
P(AandB)=360
P(AorB)=648+576-360=964
P(notAnorB)=1200-964=236
therefore the max number favoring C is 236
