If c is a positive even integer, and n and m are consecutive integers, then (n - m)^c/(m - n)^c =  Choose one.
A) -2	B) -1	C) 0	D) 1	E) 2
c= +ve even integer   Since,n and m are consecutive integers , their difference will be 1   ((n-m)^c)/((m-n)^c)= ((n-m)/(m-n))^c = (-1)^c   Since we are raising the difference of n and m to power c , which is even , the answer will be 1 .   Answer 1
