Answer 1

Answer:

(48)²

lets divide it

Step-by-step explanation:

(40+8)²

(a+b)²

a²+b²+2ab

simi...

(40)²+(8)²+2(40)(8)

1600+64+640

1600+640+64

2240+64

2304

Answer 2

Here , we can use either the identity (a+b)^2 or (a-b)^2

So , we are going to use the identity (a-b)^2 .

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

= (50-2)^2 = 50^2 + 2^2 - 2*50*2

= 2500 + 4 -200

= 2304
