Question

evalute the following using special identity 998×998

Answer 1

998 × 998 = 998^2

=> (1000-2)^2

=> 1000^2 + 2^2 - 2(1000)(2)

=> 1000000 + 4 - 4000

=> 1000004 - 4000

=> 996004

Answer 2

998 × 998 = 998^2

=> (1000-2)^2

=> 1000^2 + 2^2 - 2(1000)(2)

=> 1000000 + 4 - 4000

=> 1000004 - 4000

=> 996004
