4) a)
3²² = ( 3² )¹¹ = 9¹¹
2³³ = ( 2³ )¹¹ = 8¹¹
deduc ==> 9¹¹ > 8¹¹ ==> 3²² > 2³³
_____________________________
b)
4³³ = ( 4³ ) ¹¹ = 64¹¹
3⁴⁴ = ( 3⁴ ) ¹¹ = 81¹¹
== > 64¹¹ < 81¹¹ ==> 4³³ < 3⁴⁴
_____________________________
c)
11²² = ( 11² )¹¹ = 121¹¹ si 22¹¹
==> 121¹¹ > 22¹¹ ==> 11²² > 22¹¹
_______________________________
d)
2³⁹= ( 2³ )¹³ = 8¹³
3²⁶ = ( 3² )¹³ = 9¹²
==> 8¹³ < 9¹² ==> 2³⁹ < 3²⁶
__________________________
e)
5⁴⁵ = ( 5³ )¹⁵ = 125¹⁵
6³⁰ = ( 6² )¹⁵ = 36¹⁵
==> 125¹⁵ > 36¹⁵ ==> 5⁴⁵ > 6³⁰
_______________________________
f)
15⁹⁰ = ( 15² )⁴⁵ = 225⁴⁵
6¹³⁵ = ( 6³ )⁴⁵ = 216⁴⁵
==> 225⁴⁵ > 216⁴⁵ ==> 15⁹⁰ > 6¹³⁵
