Let x = a5 + b11 , where a>0 and b>0.

What is the largest value of x that can not be made?

#6

Hey @officialsoumalya
The numbers given are
39
35
51
41

51 can be made like: 85+111
41 can be made like: 65+111
35 and 39 can’t be made like a5+b11, so largest number that can’t bee made like a5+b11 is max(35, 39) viz 39
