Question

So sánh 3¹²⁵ và 4⁹³

Answer 1

Ta có: \(3^{125}=3^{124}.3=\left(3^4\right)^{31}.3=81^{31}.3\)

\(4^{93}=\left(4^3\right)^{31}=64^{31}\)

Vì 81³¹ > 64³¹ Nên 3¹²⁵ > 4⁹³

Answer 2

3¹²⁵ = (3⁴)³¹ . 3 = 81³¹ .3
4⁹³    = (4³)³¹ = 64³¹
Vì 81³¹.3> 64³¹ => 3¹²⁵ > 4⁹³
 

Answer 3

3¹²⁵ = (3⁴)³¹ . 3 = 81³¹ .3
4⁹³    = (4³)³¹ = 64³¹
Vì 81³¹.3> 64³¹ => 3¹²⁵ > 4⁹³
