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 

tick cái bạn

a,444^333>333^444

b3^486>4^363

c,5^217<123^72

d,31^11>17^14

5\(^{300}\)=25\(^{150}\)

3\(^{453}\)=27\(^{151}\)=27.27\(^{150}\)

vì 25\(^{150}\)<27.27\(^{150}\)

\(\Rightarrow\)5\(^{300}\)<3\(^{453}\)

31\(^{11}\)<32\(^{11}\)=(2\(^5\))\(^{11}\)=2\(^{55}\)

31\(^{11}\)<2\(^{55}\)

17\(^{14}\)>16\(^{14}\)=2\(^{56}\)

31\(^{11}\)<2\(^{55}\)<2\(^{56}\)<17\(^{14}\)

\(\Rightarrow\)31\(^{11}\)<17\(^{14}\)

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

444\(^{333}\)=4\(^{333}\).111\(^{333}\)

ta có 3\(^{444}\)=81\(^{111}\)

4\(^{333}\)=64\(^{111}\)

\(\Rightarrow\)3\(^{444}\)>4\(^{333}\)(81\(^{111}\)>64\(^{111}\))

111\(^{444}\)>111\(^{333}\)

3\(^{444}\).111\(^{444}\)>4\(^{333}\).111\(^{333}\)

Vậy 333\(^{444}\)>444\(^{333}\)

nảy mình làm thiếu 1 câu bây giờ bù nhá

Ta có: 333⁴⁴⁴ = (3.111)⁴⁴⁴ = 3⁴⁴⁴.111⁴⁴⁴ = 81¹¹¹.111⁴⁴⁴

          444³³³ = (4.111)³³³ = 4³³³.111³³³= 64¹¹¹.111³³³

Vì 81¹¹¹ > 64¹¹¹, 111⁴⁴⁴ > 111³³³ nên 81¹¹¹ . 111⁴⁴⁴ > 64¹¹¹.111³³³

  Vậy 333⁴⁴⁴ < 444³³³

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

chúc bạn học tốt

\(333^{444}\)và \(444^{333}\)

Ta có:

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

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

111 đã có cùng số mũ nên ta so sánh \(\left(333^4\right)\)và \(\left(444^3\right)\)ta đc:

\(\Rightarrow\)\(333^4=\left(3.111\right)^4=3^4.111^4=81.111^4\)

\(\Rightarrow\)\(444^3=\left(4.111\right)^3=4^3.111^3=64.111^3\)

Vì: \(81.111^4>61.111^3\)

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

Ta có: \(81=3^4>4^3=64\)

\(\Rightarrow4^3\cdot111^3< 3^4\cdot111^3< 3^4\cdot111^4\)

\(\Rightarrow444^3< 333^4\)

\(\Rightarrow\left(444^3\right)^{111}< \left(333^4\right)^{111}\)

\(\Rightarrow444^{333}< 333^{444}\)

\(\Rightarrow-333^{444}< -444^{333}\)
