Answer 2

$\huge\boxed{Question}$

1. 100² - 99² = ??
2. 27² - 26² = ??
3. 569² - 568² = ??

$\huge\boxed{Solution}$

By applying identity to solve this question

According to identity

1. 100² - 99²

= (100-99)(100+99)

= 1 × 199 = 199

2. 27² - 26²

= (27 - 26)( 27 + 26)

= 1 × 53 = 53

3. 569² - 568²

= (569-568)(569+568)

= 1 × 1137 = 1137

$\huge\boxed{Note}$

a² - b² = (a+b) (a-b)
