Răspuns:
9²¹/2011=(3²)²¹/2011=3⁴²/2011
3³¹/2011
27¹¹/2011=(3³)¹¹/2011=3³³/2011
avem aceleasi baze ale numaratorului comparam exponentul
3³¹/2011 ; 27¹¹/2011 ; 9²¹/2011
__________
2011/2³⁵=2011/(2⁵)⁷=2011/32⁷
2011/3²¹=2011/(3³)⁷=2011/27⁷
2011/5¹⁴=2011/(5²)⁷=2011/25⁷
avem acelasi exponent la numitor comparam bazele
2011/5¹⁴ ; 2011/3²¹ ; 2011/2³⁵
