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
