\(3^{450}=\left(3^3\right)^{150}=27^{150}\)
\(5^{300}=\left(5^2\right)^{150}=25^{150}\)
Do\(27>25\Rightarrow27^{150}>25^{150}\Rightarrow3^{450}>5^{300}\)
Vậy\(3^{450}>5^{300}\)
3450 = ( 33 )150 = 27150
5300 = ( 52 )150 = 25150
Mà 27 > 25; 150 = 150 \(\Rightarrow\)27150 > 25150
Vậy 3450 > 5300
Ta có: 3 ^ 450 = 3 ^ (9 * 50) = (3 ^ 9) ^ 50 = 729 ^ 50
5 ^ 300 = 5 ^ (6 * 50) = (5 ^ 6) ^ 50 = 3125 ^ 50
Vì 729 < 3125 => 729 ^ 50 < 3125 ^ 50 => 3 ^ 450 < 5 ^ 300
Vậy 3 ^ 450 < 5 ^ 300.
