Answer:

N = 16

Explanation:

The only relevant given piece of information is ...

log2(2N) = 5

2N = 2^5 = 32 . . . . . take antilogs

N = 16 . . . . . . . . . divide by 2

_____

Additional comment

From log8(N) = r/2, you have log8(N^2) = r, or ...

r = log((2^4)^2)/log(2^3) = 8/3

and ...

s = 4 +r = 20/3
