Question

So sánh :

\(2^{556}\) và \(5^{221}\)

Answer 1

2⁵⁵⁶ > 5²²¹

Answer 2

mình nhầm, xin lỗi nha

2⁵⁵⁶ > 5²²¹

Answer 3

Ta có : \(2^{556}=2^{555}.2=\left(2^5\right)^{111}.2=32^{111}.2\)

            \(5^{221}=5^{222}:5=\left(5^2\right)^{111}:5=25^{111}:5\)

Vì  \(32^{111}.2>25^{111}:5\)

nên \(2^{556}>5^{221}\)
