a) Ta có: \(27^5=\left(3^3\right)^5=3^{15}\)
\(243^3=\left(3^5\right)^3=3^{15}\)
Vậy \(27^5=243^3\)
a) Ta có: 275=(33)5 = 315
2433=(35)3 = 315
=>275=2433
b) Ta có: 31000=(310)100 = 59049100
21500=(215)100 = 32768100
Vì 59049>32768 =>59049100>32768100
=>31000>21500
c) Ta có: 1714>1614 = (24)14 =256
3111<3211=(25)11=255
Vì 1714>256>255>3111
=>1714>3117
