Answer 2

Answer:

We can use Identity III to find the solution of this given question.

Identity III = ( a + b ) ( a - b ) = a^2 - b^2

Given :-

• 1002 × 998

To Find :-

• The product of the given numbers

Solution :-

• ( 1000 + 2 ) ( 1000 - 2 )
• = 1000^2 - 2^2
• = 1000000 - 4
• = 999996

Therefore, the product is 999996.
