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