If g and s are positive integers such that (2^g)(4^s) = 16, then 2g + s =	Pick:
A) 2
B) 3
C) 4
D) 5
E) 6
lets get the eq into simplest orm..   (2^g)(4^s) = 16..   (2^g)(2^2s) = 2^4..   or g+2s=4..   since g and s are positive integers, only g as 2 and s as 1 satisfy the Equation..   so 2g+s=2*2+1=5..   5

If g and s are positive integers such that (2^g)(4^s) = 16, then 2g + s =
