A=55 X 55
A=55 X ( 54+1)
A=54X55+55
B=54 X 56
B=54 X (55+1)
B=54 X55 + 54
VÌ 54 X 55 = 54 X 55 => 54 X 55 + 55 > 54 X 55 + 54
VẬY A>B
A=55x(54+1)
=55x54+55x1
B=54x(55+1)
=54x55+54x1
Vì 55x54=54x55 ma 55x1>54x1 nên A>B
ban lam tot lam minh dang tim cau tra loi cho bai nay cam on ban
A = 55 x 55
A = 55 x (54 + 1)
A = 54 x 55 + 55
B = 54 x 56
B = 54 x (55 + 1)
B = 54 x 55 + 54
Vì 54 x 55 = 54 x 55 = > 54 x 55 + 55 > 54 x 55 + 54
Vậy A > B
