Question

. Solve by use a suitable identity (1.1m -0.4) (1.1m+0.4) *​

Answer 1

Answer:

1.21m² - 0.16

Step-by-step explanation:

( 1.1m - 0.4 ) ( 1.1m + 0.4 )

Identity : -

( a - b ) ( a + b ) = a² - b²

Here,

a = 1.1m

b = 0.4

( 1.1m - 0.4 ) ( 1.1m + 0.4 )

= ( 1.1m )² - ( 0.4 )²

= 1.21m² - 0.16
