Ta có: 333^444= 111^444 x 3^444
444^333 = 111^333 x 4^333
Tách: 3^444 = (3^4)^111 =81^111 <=>4^333 = (4^3)^111 = 64^111
Mà: {111^444 > 111^333 (1)
{81^111 > 64^111 hay: (3^4)^111 > (4^3)^111 (2)
Từ (1) và (2) ta có:333^444 > 444^333

Ta có: \(81=3^4>4^3=64\)
\(\Rightarrow4^3\cdot111^3< 3^4\cdot111^3< 3^4\cdot111^4\)
\(\Rightarrow444^3< 333^4\)
\(\Rightarrow\left(444^3\right)^{111}< \left(333^4\right)^{111}\)
\(\Rightarrow444^{333}< 333^{444}\)
\(\Rightarrow-333^{444}< -444^{333}\)

\(333^{444}=\left(3.111\right)^{444}=3^{444}.111^{444}=\left(3^4\right)^{111}.111^{444}=81^{111}.111^{444}\)
\(444^{333}=\left(4.111\right)^{333}=4^{333}.111^{333}=\left(4^3\right)^{111}.111^{333}=64^{111}.111^{333}\)
Vì 81 > 64 nên 81111 > 64111 và 111444 > 111333
=> 81111 . 111444 > 64111 . 111333
Vậy 333444 > 444333.
444^ 333 lớn hơn , bạn nào vào mục câu hỏi hay tick mk với , mk trả lại 10 tick vì mi có khá nhiều nick đó !!!

\(333^{444}=\left(111.3\right)^{444}=111^{444}.3^{444}\)
\(444^{333}=\left(111.4\right)^{333}=111^{333}.4^{333}\)
mà \(3^{444}=3^{4.111}=81^{111}\)
\(4^{333}=4^{3.111}=64^{111}\)
ta có : \(111^{444}>111^{333}\)
\(81^{111}>64^{111}\)
\(\Rightarrow333^{444}>444^{333}\)
Ta có: \(333^{444}=\left(3.111\right)^{444}=3^{444}.111^{444}\)
\(444^{333}=\left(4.111\right)^{333}=4^{333}.111^{333}\)
Ta lại có: \(3^{444}=\left(3^4\right)^{111}=81^{111}\)
\(4^{333}=\left(4^3\right)^{111}=64^{111}\)
\(\Rightarrow3^{444}>4^{333}\left(81^{111}>64^{111}\right)\)
Mặt khác: \(111^{444}>111^{333}\)
\(\Rightarrow3^{444}.111^{444}>4^{333}.111^{333}\)
Vậy \(333^{444}>444^{333}\)
