\(333^{444}=\left(333\times4\right)^{111}=1332^{111}\)

\(444^{333}=\left(444\times3\right)^{111}=1332^{111}\)

\(1332^{111}=1332^{111}\Rightarrow333^{444}=444^{333}\)

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

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

\(\Rightarrow333^4=111^4.3^4=111^3.111.3^4\)

     \(444^3=111^3.4^3\)

\(\Rightarrow111.3^4=111.81>4^3=64\)

\(\Rightarrow333^{444}>444^{333}\)

Ta có: 333⁴⁴⁴=333^111.4=333⁴mũ 111=12296370321¹¹¹

              444³³³=444^111.3=444³mũ 111=87528384¹¹¹

Mà: 12296370321>87528384 và 111=111.

=>333⁴⁴⁴>444³³³.

Tk phát nhé

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 

So sánh A và B ta thấy:

 A<B

**** nha

C = 2³³³ = (2³)¹¹¹ = 8¹¹¹

D = 3²²² = (3²)¹¹¹ = 9¹¹¹

Vì  8¹¹¹ < 9¹¹¹

Nên : C < D 

1) A=333⁴⁴⁴ và B=444³³³

Ta có 333⁴⁴⁴=(3.111)^4.111=3^4.111.111^4.111=(3⁴.111⁴)¹¹¹=(81.111⁴)¹¹¹

444³³³=(4.111)^3.111=4^3.111.111^3.111=(4³.111³)¹¹¹=(64.111³)¹¹¹

Vì (81.111⁴)¹¹¹> (64.111³)¹¹¹

Nên 333⁴⁴⁴ > 444³³³

2) C=2³³³ và D=333²²²

Ta có 2³³³=2^3.111=(2³)¹¹¹=8¹¹¹

3²²²=3^2.111=(3²)¹¹¹=9¹¹¹

Vì 8¹¹¹ <9¹¹¹

Nên 2³³³< 3²²²

a)\(9^{12}=\left(3^2\right)^{12}=3^{24}\)

 \(27^7=\left(3^3\right)^7=3^{21}\)

\(\Rightarrow9^{12}>27^7\)

a) bạn Mạnh làm rồi và đúng

b) Ta có : \(333^{444}=\left(333^4\right)^{111}=\left[\left(3.111\right)^4\right]^{111}=\left[\left(3^4.111^4\right)\right]^{111}=\left(84.111^4\right)^{111}\)

                \(444^{333}=\left(444^3\right)^{111}=\left[\left(4.111\right)^3\right]^{111}=\left[\left(4^3.111^3\right)\right]^{111}=\left(64.111^3\right)^{111}\)

Ta thấy (84.111⁴)¹¹¹ > ( 64.111³)¹¹¹ => 333⁴⁴⁴ > 444³³³

Vậy...

c) Vì \(17^{2002}+1>17^{2001}+1\)

\(\Rightarrow\frac{17^{2001}+1}{17^{2002}+1}< \frac{17^{2001}+1}{17^{2001}+1}\)
