\(10^{200}=\left(5^2\right)^{200}=5^{400}\)
\(=>5^{400^{ }}=10^{200}\)
5^400 và 10^200
5^400=(5^2)^200=25^200>10^200 vậy 5^400>10^200
5^400=5^100x4=5x4^100=20 mũ 100
10 mũ 200=10^2x100=10x2^100=20 mũ 100
=>5 mũ 400 bằng 10 mũ 200
ta co
\(5^{400}\)=\(\left(5^2\right)^{200}\)=\(25^{200}\)>\(10^{200}\)
\(5^{400}=\left(5^4\right)^{100}=625^{100}\)
\(10^{200}=\left(10^2\right)^{100}=100^{100}\)
Vì 625 > 100
\(\Rightarrow5^{400}>10^{200}\)
5400 = ( 5 x 2 )200 ; 10200
= 10200 ; 10200
vì 10200 = 10200 nên 5400 = 10200
Ta có:
5400=(54)100=625100
10200=(102)100=100100
Vì 625100>100100 nên 5400>10200
5400=54x100=(54)100=625100
10200=102x100=(102 )100=100100
vì 625>100 nên 625100>100100
vậy 5400>10200
