Answer 1

Hi pupil here's your answer ::

_______________________________

32#2 is the answer because: all of them come in the tables for their smaller numbers for example ::
3#27 :: 27 comes in the table of 3 by 9 places
72#8 :: 72 comes in the table of 72 by9 places
18#54 :: 53 comes in the table of 18 by3 places
but
32#2 32 doesn't come in the table of 2 but it is 2^5
