Question

so sanh phep tinh 3⁴⁸⁴ va 4³⁶³

Answer 1

\(3^{484}=\left(3^4\right)^{121}=81^{121}\)

\(4^{363}=\left(4^3\right)^{121}=64^{121}\)

Vì 81 > 64 nên 81¹²¹ > 64¹²¹ hay 3⁴⁸⁴ > 4³⁶³ 

Vậy 3⁴⁸⁴ > 4³⁶³

Answer 2

\(3^{484}=\left(3^4\right)^{121}=81^{121}\)

\(4^{363}=\left(4^3\right)^{121}=64^{121}\)

=> \(64< 81\Rightarrow64^{121}< 81^{121}\Rightarrow4^{363}< 3^{484}\)

Answer 3

xét 3⁴⁸⁴= (3⁴)¹²¹= 81¹²¹

xét 4³⁶³= (4³)¹²¹= 64¹²¹

mà  81¹²¹ >  64¹²¹

=>3⁴⁸⁴ > 4³⁶³

Vậy 3⁴⁸⁴ > 4³⁶³

Answer 4

Xét 3^484=(3^4)^121=81^121

4^363=(4^3)^121=64^121

Vì 81>64 nên 81^121>64^121 hay 3^484>4^363

Vậy 3^484>4^363
