n^200<5^300=>(n^2)^100<(5^3)^10;0=>n^2<5^3=125=>n^2={0;4;9;...;121}
ma n lon nhat=>n^2=121=>n=11
tick nhe

Ta có : \(n^{200}=\left(n^2\right)^{100};5^{300}=\left(5^3\right)^{100}=125^{100}\)
Để: \(n^{200}< 5^{300}\Rightarrow\left(n^2\right)^{100}< 125^{100}\Leftrightarrow n^2< 125\)\(\Leftrightarrow n=11\)
![](https://rs.olm.vn/images/avt/0.png?1311)
\(5^{300}=\left(5^3\right)^{100}=125^{100}\)
\(n^{200}=\left(n^2\right)^{100}\)
n=12
![](https://rs.olm.vn/images/avt/0.png?1311)
Ta có: \(n^{200}<5^{300}\)=> \(n^{2\cdot100}<5^{3\cdot100}=>\left(n^2\right)^{100}<\left(5^3\right)^{100}\Leftrightarrow n^2<5^3\Leftrightarrow n^2<125\)\(\Rightarrow n^2\in\left\{0;1;4;9;16;25;36;49;64;81;100;121\right\}\)
mà n >0
\(=>n\in\left\{1;2;3;4;5;6;7;8;9;10;11\right\}\)
mà n là số nguyên dương lớn nhất
=> n = 11
Vậy n =11
![](https://rs.olm.vn/images/avt/0.png?1311)
N^200<5^300
=>(n^2)^100<(5^3)^100
=>n^2<5^3=125
=>n^2={0;4;9;...;121}
Ma n lon nhat=>n=11
Tick đi

\(n^{200}<5^{300}=>\left(n^2\right)^{100}<\left(5^3\right)^{100}=>n^2<5^3=125=>n^2\in\left\{0;4;9;...;121\right\}\)
mà n lớn nhất nên n^2=121=>n=11
tick nhé
![](https://rs.olm.vn/images/avt/0.png?1311)
n^200<5^300=>(n^2)^100<(5^3)^100
=>n^2<5^3=125
=>n^2 thuộc {0;4;9;...;121}
mà n lớn nhất=>n^2=121=>n=+11
mà n nguyên dương =>n=11
tick nhé
