Question

(99.2) square -(0.1) square

Answer 1

( 99.2 )² - ( 0.1 )²

$<b>a² - b² = ( a + b ) ( a - b )</b>$

= ( 99.2 + 0.1 ) ( 99.2 - 0.1 )

= 99.3 × 99.1

= 9,840.63

Answer 2

Answer:

( 99.2 )² - ( 0.1 )²

a² - b² = ( a + b ) ( a - b )

= ( 99.2 + 0.1 ) ( 99.2 - 0.1 )

= 99.3 × 99.1

= 9,840.63
