2570=(52)70=5140=(57)20=7812520
2300=(215)20=3276820
=>2570>2300
2570 = (52) 70 = 5140 = (57) 20 = 7812520
2300 =(215) 20 = 3276820
=> 2570 > 2300
chúc bạn học tốt.
ta có: \(25^{70}=\left(5^2\right)^{70}=5^{140}=\left(5^7\right)^{20}=78125^{20}\)
\(2^{300}=\left(2^{15}\right)^{20}=32768^{20}\)
Vì 78125 > 32768 nên 2570 > 2300
ta có: \(25^{70}=\left(5^2\right)^{70}=5^{140}=\left(5^7\right)^{20}=78125^{20}\)
\(2^{300}=\left(2^{15}\right)^{20}=32768^{20}\)
Vì 78125 > 32768 nên 2570 > 2300
\(25^{70}=\left(5^2\right)^{70}=5^{140}\)
\(2^{300}=\left(2^2\right)^{150}=4^{150}\)
\(5^{140}>4^{150}\)
