Answer & Solution
Correct Answer:
Option
B
Given Exp.
= (397)2 + (104)2 + 2 × 397 × 104
= (397 + 104)2
= (501)2 = (500 + 1)2
= (5002) + (1)2 + (2 × 500 × 1)
= 250000 + 1 + 1000
= 251001
= (397)2 + (104)2 + 2 × 397 × 104
= (397 + 104)2
= (501)2 = (500 + 1)2
= (5002) + (1)2 + (2 × 500 × 1)
= 250000 + 1 + 1000
= 251001
