Đọc tiếp
a)
ta có \(3^{600}=\left(3^2\right)^{300}=9^{300}\)
\(\Rightarrow9^{300}\)> \(6^{300}\)
vậy \(^{6^{300}}\) <\(3^{600}\)
b)
ta có \(2^{333}=\left(2^3\right)^{111}\)=\(8^{111}\)
\(3^{222}=\left(3^2\right)^{111}=9^{111}\)
vậy \(2^{333}< 3^{222}\)
c)
ta có \(99^{20}=\left(99^2\right)^{10}=9801^{10}\)
\(9999^{10}\)
vậy \(99^{20}< 9999^{10}\)
