Ta có: 333⁴⁴⁴=(111.3)^111.4=(111⁴.3⁴)¹¹¹=(111⁴.81)¹¹¹

444³³³=(111.4)^111.3=(111³.4³)¹¹¹=(111³.64)¹¹¹

mà 111⁴.81>111³.64 => 333⁴⁴⁴>444³³³

hoặc cách này :

ta có : 333⁴⁴⁴=(3.111)⁴⁴⁴=3⁴⁴⁴.111⁴⁴⁴

444³³³=(4.111)³³³=4³³³.111³³³

ta lại có: 3⁴⁴⁴=(3⁴)¹¹¹=81¹¹¹

4³³³=(4³)¹¹¹=64¹¹¹

=>3⁴⁴⁴>4³³³ ( vì 81¹¹¹>64¹¹¹)

mặt khác 111⁴⁴⁴>111³³³(vì 444>333)

suy ra : 3⁴⁴⁴.111⁴⁴⁴>4³³³.111³³³

hay 333⁴⁴⁴>444³³³

Ta có:333^444=(3x111)^4x111

         333^444=(3^4)^111

         333^444=81^111

Ta có:444^333=(4x111)^3x111

         444^333=(4^3)^111

         444^333=64^111

Vì 81 > 64.Nên 81^111 > 64^111

Vậy 333^444 > 444^333.   

\(333^{444}=333^{3^{111}}\) 

\(444^{333}=444^{3^{111}}\)

Vì \(444^{3^{111}}>333^{3^{111}}\)

=> \(333^{444}< 444^{333}\)

Ta có: \(333^{444}=\left(333^4\right)^{111}\)

           \(444^{333}=\left(444^3\right)^{111}\)

Vì 333⁴⁴⁴ và 444³³³ có cùng số mũ là 111. nên ta so sánh 333⁴ và 444³

333⁴=(3.111)⁴=3⁴.111⁴=81.111⁴

444³=(4.111)³=4³.111³=64.111³

Vì 81.111⁴>64.111³ => 333⁴>444³

=> 333⁴⁴⁴ > 444³³³

\(^{333^{444}>444^{333}}\)

Ta có:

333⁴⁴⁴ = 111⁴⁴⁴.3⁴⁴⁴ = 111⁴⁴⁴.(3⁴)¹¹¹ = 111⁴⁴⁴.81¹¹¹

444³³³ = 111³³³.4¹¹¹ 

Vì 111³³³.4¹¹¹ < 111⁴⁴⁴.81¹¹¹

=> 444³³³ < 333⁴⁴⁴

Ta có:

333⁴⁴⁴ = 111⁴⁴⁴.3⁴⁴⁴ = 111⁴⁴⁴.(3⁴)¹¹¹ = 111⁴⁴⁴.81¹¹¹

444³³³ = 111³³³.4¹¹¹ 

Vì 111³³³.4¹¹¹ < 111⁴⁴⁴.81¹¹¹

=> 444³³³ < 333⁴⁴⁴

Ta có : 

333⁴⁴⁴ = (111 . 3)⁴⁴⁴ = 111⁴⁴⁴ . 3⁴⁴⁴ = 111⁴⁴⁴ . (3⁴)¹¹¹ = 111⁴⁴⁴ . 81¹¹¹

444³³³ = (111 . 4)³³³ = 111³³³ . 4³³³ = 111³³³ . (4³)¹¹¹ = 111³³³ . 64¹¹¹

Vì 111⁴⁴⁴ . 81¹¹¹ > 111³³³ . 64¹¹¹

=> 333⁴⁴⁴ > 444³³³

Ủng hộ mk nha !!! ^_^

bang nhau

nho k minh nha

Ta có:333⁴⁴⁴=111⁴⁴⁴.3⁴⁴⁴

444³³³=111³³³.4³³³

Ta lại có:3⁴⁴⁴=(3⁴)¹¹¹=81¹¹¹

4³³³=(4³)¹¹¹=64¹¹¹

Vì 81¹¹¹>64¹¹¹ và 111⁴⁴⁴>111³³³

nên 333⁴⁴⁴>444³³³

333⁴⁴⁴>444³³³

Ta có: 333444=111444.3444 
444333=111333.4333
Tách: 3444=(34)111=81111<=>4333=(43)111=64111
Mà: 111444>111333(1)
81111>64111 hay: (34)111>(43)111(2)
Từ (1) và (2) ta có:333444>444333

ta co333^444= [111x3]^111x4

444^333=[111x4]^111x3

va ta co111^4x81>111^3x64=>333^444>444^333

333⁴⁴⁴=(111*3)⁴⁴⁴=111⁴⁴⁴*3⁴⁴⁴=111⁴⁴⁴*3^4*111=111⁴⁴⁴*81¹¹¹

444³³³=(111*4)³³³=111³³³*4³³³=111³³³*4^3*111=111³³³*64¹¹¹

Mả 111⁴⁴⁴>111³³³ ; 81¹¹¹>64¹¹¹ suy ra 333⁴⁴⁴>444³³³

333⁴⁴⁴>444³³³

333⁴⁴⁴ =( 333⁴ )¹¹¹

444³³³ = ( 444³ )¹¹¹

Theo mình nghĩ thì 333⁴⁴⁴ > 444³³³ vì 333⁴ > 444³
