If a i = a ( i + j )= a ( i + j + k ) , then a is equal to

Options

  1. Ai
  2. Bj
  3. Ck
  4. Di + j + k

Correct answer

A. i

Step-by-step solution

We have aligned & a i = a ( i + j )= a i + a j a j =0 & Also, a i = a ( i + j + k ) & a i + a j = a i + a j + a k & a k =0 & Also, i j = j k = k i =0 & Then a = i & aligned
