If x and y are positive odd integers, then which of the following must also be an odd integer? I. x^(y+2) II. x(y+3) III. (y+1)^(x-1) + 1
Choose the correct option:
A) I only  B) I,III only  C) II only  D) III only  E) II,III only
let x= 5, y= 3   I. 5^5 = &gt; Odd   II. 5*6 = &gt; even   III. 4^4 +1 = &gt; Odd   Answer : I,III only
