a. \(5^{127}=5.5^{126}=5.125^{72}>119^{72}\)

\(\Rightarrow5^{217}>119^{72}\)

b. \(2^{1000}=\left(2^5\right)^{200}=32^{200}\)

\(5^{400}=\left(5^2\right)^{200}=25^{200}\)

\(\Rightarrow2^{1000}>5^{400}\)

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

\(27^7=\left(3^3\right)^7=3^{21}\)

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

d. \(125^{80}=\left(5^3\right)^{80}=5^{240}\)

\(25^{118}=\left(5^2\right)^{118}=5^{236}\)

\(\Rightarrow125^{80}>25^{118}\)

e. \(5^{40}=\left(5^4\right)^{10}=625^{10}\)

\(\Rightarrow5^{40}>620^{10}\)

f. \(27^{11}=\left(3^3\right)^{11}=3^{33}\)

\(81^8=\left(3^4\right)^8=3^{32}\)

\(\Rightarrow27^{11}>81^8\)

ai giúp mình nhanh đc ko

\(a,3^{39}=\left(3^3\right)^{13}=9^{13}< 11^{13}< 11^{21}\\ b,2^{91}=\left(2^{13}\right)^7=8192^7< 3125^7=\left(5^5\right)^7=5^{35}\)

Đây bạn nhé! Chữ hơi xấu, thông cảm

\(8^5=\left(2^3\right)^5=2^{15}=2.2^{14}\)

\(3.4^7=3.\left(2^2\right)^7=3.2^{14}\)

Vì 2 < 3 nên 8⁵ < 3 . 4⁷

8^5<3.4^7

\(3333^{4444}=\left(1111\right)^{3.4444}=1111^{13332}\)

\(4444^{3333}=1111^{4.3333}=1111^{13332}\)

Vậy = nhau

cảm ơn !

Câu 1: 3^23  >    5^12

Câu 2: 3^36 < 2^8.11^4

4⁵⁰=  ( 4³ ) ^50/3 = 64 ^50/3

8³⁰ =( 8² ) ¹⁵ = 64¹⁵

ta có 50/3 > 15 => 4⁵⁰ > 8³⁰

\(4^{50}\)= \(\left(2^2\right)^{^{50}^{ }}\)\(=2^{100}\)

\(8^{30}=\left(2^3\right)^{30}=2^{90}\)

vì \(2^{100}>2^{90}\)nên\(4^{50}>8^{30}\)

\(333^{444}=333^{3^{111}}\) 

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

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

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

3^15>26.3^15

bn giải thích đk

3³⁰⁰ > 2³⁰⁰ ( vì 3 > 2 ).

3^200 = (3^2)^100 = 9^100 

2^300 = (2^3)^100 = 8^100 

Vì 9^100 > 8^100 

Vậy 3^200 > 2^300
