333⁴⁴⁴ = (111.3)⁴⁴⁴ = 111⁴⁴⁴.3⁴⁴⁴

444³³³ = (111.4)³³³ = 111³³³.4³³³

\(\Rightarrow\)111⁴⁴⁴>111³³³  ;  3⁴⁴⁴ = (3⁴)¹¹¹ = 81¹¹¹

                                4³³³ = (4³)¹¹¹ = 64¹¹¹

Vì 111⁴⁴⁴>111³³³ và 81¹¹¹> 64¹¹¹ nên (111⁴⁴⁴.3⁴⁴⁴) > (111³³³.4³³³) và 333⁴⁴⁴ > 444³³³

A=(3.111)^4.111=(3⁴)¹¹¹.(111⁴)¹¹¹=81¹¹¹.(111⁴⁴⁴

B=(4.111)^3.111=(4³)¹¹¹.(111³)¹¹¹=64¹¹¹.111³³³

81¹¹¹>64¹¹¹; 111⁴⁴⁴>111³³³ => A>B

Ta có : 

\(333^{444}=\left(3.111\right)^{444}=3^{444}.111^{444}=\left(3^4\right)^{111}.111^{444}=81^{111}.111^{444}\)

\(444^{333}=\left(4.111\right)^{333}=4^{333}.111^{333}=\left(4^3\right)^{111}.111^{333}=64^{111}.111^{333}\)

Vì \(81^{111}>64^{111}\) và \(111^{444}>111^{333}\)

nên \(81^{111}.111^{444}>64^{111}.111^{333}\)

Vậy \(333^{444}>444^{333}\)

tích mình nha !!!

A=333^444=111^3.444=111^1332

B=444^333=111^4.333=111^1332

=>A=B

333^444>444^333

`@` `\text {Answer}`

`\downarrow`

Ta có:

\(333^{444}=\left(333^4\right)^{111}=\left(3^4\cdot111^4\right)^{111}=\left(81\cdot111^4\right)^{111}=81^{111}\cdot111^{444}\)   `(1)`

\(444^{333}=\left(444^3\right)^{111}=\left(4^3\cdot111^3\right)^{111}=\left(64\cdot111^3\right)=64^{111}\cdot111^{333}\) `(2)`

Vì \(81>64\), \(444>333\) 

`=>`\(81^{111}>64^{111},\) \(111^{444}>111^{333}\) `(3)`

Từ `(1), (2)` và `(3)`

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

333^444>444^333

a) Do 300 < 450

⇒ 3³⁰⁰ < 3⁴⁵⁰

b) 333⁴⁴⁴ = (333⁴)¹¹¹ = (111⁴.3⁴)¹¹¹

444³³³ = (444³)¹¹¹ = (111³.4³)¹¹¹

Do 4 > 3 nên 111⁴ > 111³ (1)

Lại có:

3⁴ = 81

4³ = 64

Do 81 > 64 nên 3⁴ > 4³ (2)

Từ (1) và (2) ⇒ 111⁴.3⁴ > 111³.4³

⇒ (111⁴.3⁴)¹¹¹ > (111³.4³)¹¹¹

Vậy 333⁴⁴⁴ > 444³³³

A=333^444

A=(333^4)^111

A=1332^111

B=444^333

B=(444^3)^111

B=1332^111

Vì 1332^111=1332^111

Nên => A=B

333^444=333^(4.111)=(333^4)^111

444^333=444^(3.111)=(444^3)^111

So sánh 333^4 với 444^3:

333^4=(111.3)^4=111^4.3^4=111^4.81

444^3=(111.4)^3=111^3.4^3=111^3.64

Vì 111^4.81>111^3.64 => 333^4>444^3 => A>B.

\(A=333^{444}=\left(3.111\right)^{444}=3^{444}.111^{444}=\left(3^4\right)^{111}.111^{444}=81^{111}.111^{444}\)

\(B=444^{333}=\left(4.111\right)^{333}=4^{333}.111^{333}=\left(4^3\right)^{111}.111^{333}=64^{111}.111^{333}\)

Vì 81¹¹¹ > 64¹¹¹ và 111⁴⁴⁴ > 111³³³

=> 81¹¹¹.111⁴⁴⁴ > 64¹¹¹.111³³³

hay 333⁴⁴⁴ > 444³³³

Vậy A > B.

A > B
