\(A=333^{444}=\left(3.111\right)^{444}=3^{444}.111^{444}=\left(3^4\right)^{111}.111^{444}=81^{111}.111^{444}\)
\(B=444^{333}=\left(4.111\right)^{333}=4^{333}.111^{333}=\left(4^3\right)^{111}.111^{333}=64^{111}.111^{333}\)
Vì 81111 > 64111 và 111444 > 111333
=> 81111.111444 > 64111.111333
hay 333444 > 444333
Vậy A > B.
