Question

So sánh 25 mũ 118 và 125 mũ 80

Answer 1

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

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

Vì 236<240 suy ra \(5^{236}< 5^{240}\Leftrightarrow25^{118}< 125^{80}\)

Answer 2

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

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

vi \(5^{236}< 5^{240}\) nen \(25^{118}< 125^{80}\)

Answer 3

25¹¹⁸ = (5²)¹¹⁸ = 5²³⁶

125⁸⁰ = (5³)⁸⁰ = 5²⁸⁰

Vì 5²³⁶ < 5²⁸⁰ nên 25¹¹⁸ < 125⁸⁰

Answer 4

25¹¹⁸=(5²)¹¹⁸=5²³⁶

125⁸⁰=(5³)⁸⁰=5²⁴⁰

=> 5²³⁶< 5²⁴⁰( vì 236<240)

Answer 5

Ta có :

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

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

Vì \(5^{236}< 5^{240}\Rightarrow25^{18}< 125^{80}\)

Answer 6

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

Ta có:\(125^{80}=\left(5^3\right)^{80}=5^{240}\)

VÌ 236<240\(\Rightarrow\)\(5^{236}< 5^{240}\Rightarrow25^{118}< 125^{80}\)
