\(599^{93}=\left(599^3\right)^{31}\)
\(139^{124}=\left(139^4\right)^{31}\)
Ta dễ thấy: \(599^3>139^4\) nên:
\(\left(599^3\right)^{31}>\left(139^4\right)^{31}\Rightarrow599^{93}>139^{124}\)
59993 = 5993x31 = (5993)31
139124 = 1394x31 = (1394)31
Do 1394 > 1254 = (53)4 = (54)3 = 6253 > 5993
Nên 139124 > 59993
