1)given :-

496*504 = (500-4) *(500+4)

identity used here :-

(a-b)(a+b) = a²-b²

step by step answer :-

(500-4)×(500+4)  = (500)² - (4)²

                            =250000 - 16

496*504             =   249984

496*504 = 249984 is ur answer

----------------------------------------------------------------------------------

2) given :-

20.5*19.5 = (20+0.5) * (20-0.5)

identity used here :-

(a+b)(a-b) = a²-b²

step by step answer :-

(20+0.5) * (20-0.5)= 20² - 0.5²

                             = 400 - 0.25

(20+0.5) * (20-0.5) =399.75

(20+0.5) * (20-0.5) =399.75 is ur answer

-----------------------------------------------------------------

3) given :-

9.6²=(10-0.4)²

identity used here :-

(a-b)²=a²-2ab+b²

step by step answer :-

(10-0.4)² = 10²-2*0.4*10+[0.4]²

               = 100+0.16-8

(10-0.4)²      = 92.16

(10-0.4)² = 92.16 is ur answer
