let log4(base2)=p
therefore 2^p=4
so p = 2,
Again log8(base2)=p
therefore 2^p=8
so p = 3,
Last Again log16(base2)=p
therefore 2^p=16
so p=4,
By the possibility
let last value be logx(base2)=p
but by the condition, p should be 5
therefore 5=logx(base2)
represent in square form 2^5=x
so x = 32
p=log32(base2)
