a) 6²² = ( 6² ) ¹¹ = 36¹¹
2⁵⁵ = ( 2⁵ )¹¹ = 32¹¹
==> 36¹¹ > 32¹¹ ==> 6²² > 2⁵⁵
_________________________
b) 3²¹ si 6¹⁴
3²¹ = ( 3³ ) ⁷ = 27⁷
6¹⁴ = ( 6² )⁷ = 36⁷
== > 27⁷ < 36⁷ == > 3²¹ < 6¹⁴
_________________________
f) 4²⁹ si 7 ¹⁸ x 16
4²⁹ = ( 2² ) ²⁹ = 2⁵⁸ = 2⁴ x 2⁵⁴= 2⁴ x ( 2³ ) ¹⁸ = 2⁴ x 8¹⁸
2⁴ x 8¹⁸ > 7¹⁸ x 2⁴ ==> 4²⁹ > 7¹⁸ x 16
________________________________
g) 5³⁴ x 9 si 3⁵³
5³⁴ x 9 = ( 5² ) ¹⁷ x 9 = 25¹⁷x 9
3⁵³ = 3² x 3⁵¹ = 9 x ( 3³ ) ¹⁷ = 9 x 27¹⁷
==> 25¹⁷ x 9 < 9 x 27¹⁷ ==> 5³⁴ x 9 < 3⁵³
