Ta co : \(3^{500}\&7^{300}\)
\(\Rightarrow3^{500}=\left(3^5\right)^{100}=243^{100}\)
\(\Rightarrow7^{300}=\left(7^3\right)^{100}=343^{100}\)
Ta thay \(243^{100}
3^500=(3^5)^100=243^100
7^300=(7^3)^100=343^100
3500 = 35.100 = ( 35)100
7300 = 73.100 = ( 73)100
Vì 35 < 73 nên => 3500 < 7300
Vì
\(3^{500}=\left(3^5\right)^{100}\)
\(7^{300}=\left(7^3\right)^{100}\)
và
\(3^5=243\)
\(7^3=343\)
\(\Rightarrow3^5< 7^3\)
Vậy \(3^{500}< 7^{300}\)
3500=(35)100=243100
7300=(73)100=343100
243100<343100
=>3500<7300
