5533 = (553)11 = 16637511
3355 = ( 335 )11 = 3913539311
mà 16637511 < 3913539311
=> 5533 < 3355
Chúc bạn học tốt !
\(55^{33}=\left(55^3\right)^{11}=166375^{11}\)
\(33^{55}=\left(33^5\right)^{11}=39135393^{11}\)
Vì : \(166375^{11}< 39135393^{11}\)
Vậy : \(55^{33}< 33^{55}\)
\(55^{33}=\left(55^3\right)^{11}\)=\(\left(11^3.5^3\right)^{11}\)
\(33^{55}=\left(33^5\right)^{11}\)\(=\left(11^5.3^5\right)^{11}\)
Vì 113 < 115 ; 53 < 35
=> (115 . 35)11 > (113 . 53)11
Nên : 553 < 335
Vậy : 5533 < 3355
