Answer 1

Given:

• 297×303

To Find:

• The value of the given by using Identity

Solution:

We can write

☞ 297 = 300-3 & ☞ 303 = 300+3

$→\;{\sf{297×303}}$

$→\;{\sf{(300-3)(300+3)}}$

✯ $\blue{\bold{(a+b)(a-b) = a²-b²}}$

$→\;{\sf{(300)²-(3)²}}$

$→\;{\sf{90000-9}}$

$➝\;{\bf{89,991}}$

SoLuTiOn

We can write

☞297 = 300-3 & 303 = 300 + 3

☞297 × 303

☞(300-3)(300+3)

☞( a + b) (a - b) = a² - b²

☞300² - 3²

☞90000 - 9

= 89,991
