Answer 1

Answer:

996004

Step-by-step explanation:

→ (998)^2

→ (1000 - 2)²

We did 1000 - 2, as square of 1000 and 2 can be found easily, in comparison of any other pair or 998 it self.

Using (a - b)² = a² + b² - 2ab

→ (1000)² + (2)² - 2(2*1000)

→ 1000000 + 4 - 4000

→ 996004

Answer 2

Answer:

Your answer is 996,004

plz mark me as brainliest

Step-by-step explanation:

(998)^2

(1,000-2)^2

we have done that because now we will find the square in easiest way

NOWW BY USING THIS FORMULA (a-b)^2=a^2+b^2 -2ab/a^2-2ab+b^2

1,000^2-2(1,000)(2)+2^2

1,000,000-4,000+4

NOW YOU CAN ONLY ADD AND SUBTRACT AND YOU WILL GET YOUR ANSWER

996,000+4

996,004
