a)
32^13=(2^5)^13=2^65
8^21=(2^3)^21=2^63
=> 32^13 > 8^21

b)
8^17=(2^3)^17=2^51
16^12=(2^4)^12=2^48
=> 8^17 > 16^12

c)
27^13=(3^3)^13=3^39
9^20=(3^2)^20=3^40
=> 27^13 < 9^20

d)
3^27
9^13=(3^2)^13=3^26
=> 3^27 > 9^13

e)
2^33=(2^3)^11=8^11
3^22=(3^2)^11=6^11
=> 2^33 > 3^22

f)
2^51=(2^3)^17=8^17
3^34=(3^2)^17=6^17
=> 2^51 > 6^17

g)
4^115=(4^5)^23=1024^23
5^92=(5^4)^23=625^23
=> 4^115 > 5^92
