Question

$find \: the \: value \: of \: 998 \: \times \: 1002 \: usimg \: formula$
​

Answer 1

Answer:

$998 \times 1002$

$(1000 - 2)(1000 + 2)$

$by \: using \: this \: formula {x}^{2} - {y}^{2} = (x + y)(x - y)$

${1000}^{2} - {2}^{2}$

$1000000 - 4$

$999996$

Answer 2

998×1002

(1000 - 2)(1000 + 2)

by using this formula x²-y² =

(x + y) (x -y)

1000²-2²

1000000-4

999996
