A < B 

HT

Đặt \(2021=a\), khi đó \(A=a^3\)và \(B=a\left(a-1\right)\left(a+1\right)\)

Ta có: \(B=a\left(a-1\right)\left(a+1\right)=\left(a^2-a\right)\left(a+1\right)=a^3+a^2-a^2-a=a^3-a\)

Vì \(a>0\)nên hiển nhiên ta có \(B=a^3-a< a^3=A\)

Vậy \(A>B\)

Trả lời

D

Answer:

Chiều dài

\(48:\left(5-3\right)\times5=120m\)

Chiều rộng

\(120-48=72m\)

Diện tích

\(120\times72=8640m^2\)
