Question

So sánh A và B biết rằng:

A = 333⁵⁵⁵

B=555³³³

 

Answer 1

A = 333⁵⁵⁵ = (3.111)⁵⁵⁵ = 3⁵⁵⁵.111⁵⁵⁵ = (3⁵)¹¹¹.111⁵⁵⁵ = 243¹¹¹.111⁵⁵⁵

555³³³ = (5.111)³³³ = 5³³³.111³³³ = (5³)¹¹¹.111³³³ = 125¹¹¹.111³³³

Vì 243¹¹¹.111⁵⁵⁵ > 125¹¹¹.111³³³

=> 333⁵⁵⁵ > 555³³³

hay A > B

Answer 2

\(vi333^{555}>555^{333}nenA>B\)
