Correct answer
C. 2
Step-by-step solution
Let A = [ ( 1 + 1 10000 ) 10000 ] = [ ( 1 + 0 . 0001 ) 1000 ] We know that, ( 1 + x ) n = C 0 n + C 1 n · x + C 2 n · x 2 + C n n · x n A = [ C 0 1000 + C 1 1000 · ( 0 . 0001 ) + C 2 1000 · ( 0 . 0001 ) 2 + . . . . . . + C 1000 1000 · ( 0 . 0001 ) n ] A = [ 1 + 10000 × 0 . 0001 + 10000 × 999 2 × 10 - 8 + . . . . . . . . ] A = [ 1 + 1 + 0 . 49 + . . . ] A = [ 2 . 049 + . . . ] A = 2 .
