Question

Evaluate using the suitable identity (3.6 ×3.6+2×3.6 ×1.4+1.4×1.4)/(5.6-0.6)

Answer 1

Answer:

we have given

3.6 x 3.6 + 2 x 3.6 x 1.4 + 1.4 x 1.4

5.6 - 0.6

it can be written as

( 3.6 )^2 + 2 x 3.6 x 1.4 + ( 1.4 )^2

5

Step-by-step explanation:

(3.6)^2 + 2 x 3.6 x 1.4 + (1.4)^2

(a)^2 + 2ab + (b)^2 = ( a + b )^2

(3.6)^2 + 2 x 3.6 x 1.4 + (1.4)^2 = ( 3.6 + 1.4 )^2

here , a = 3.6 and b = 1.4
