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

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

=> \(5^{236}< 5^{240}\Rightarrow25^{118}< 125^{80}\)

vậy...

Vì \(125^{118}>25^{118}\)

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

\(25^{12}=\left(5^2\right)^{12}=5^{24}\)

\(125^8=\left(5^3\right)^8=5^{24}\)

Do \(5^{24}=5^{24}\)

\(\Rightarrow25^{12}=125^8\)

\(25^{12}=\left(5^2\right)^{12}=5^{24}\)

\(125^8=\left(5^3\right)^8=5^{24}\)

\(\Rightarrow25^{12}=125^8\)

a) 125⁸⁰=Math ERROR
342.348=119016<Math ERROR
b) 10³⁰=(10³)¹⁰=1000¹⁰<1000²⁰

Ta có : 125^80=(5^3)^80=5^240

           25^118=(5^2)^118=5^236

   Vì 240 > 236 nên 5^240 > 5^236

                  Vậy 125^80 > 25^118

25¹¹ > 125⁷

3⁵⁴ > 2⁸¹

\(a,4^{333}=\left(4^3\right)^{111}=64^{111}< 81^{111}=\left(3^4\right)^{111}=3^{444}< 3^{445}\\ b,39^{15}>36^{15}=\left(6^2\right)^{15}=6^{30}\\ c,25^{45}=\left(5^2\right)^{45}=5^{90}< 5^{102}=\left(5^3\right)^{34}=125^{34}\)

5^18  

5^16

Trả lời

125⁶ > 25⁸

3⁵⁰ > 2⁷⁵

Học tốt nha !

trả lời 

\(125^6>25^8\)

\(3^{50}>2^{75}\)

hc tốt
