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