Chromatography, Change of efficency required to double the resolution?

I've stumbled upon a problem which I think i've misunderstood.
The question at hand is "How do you change the efficency(or number of "bottoms" as its called in swedish) to double the resolution?"

Naturally, i thought it was just to expand the formula by multiplying by 2 on both sides of the equation:

R=(sqrt(N)/4) * ((S-1)/S) * ((k')/(1+k'))

Where R=Resolution
N=efficency(number of "bottoms")
S=Selectivity
k'=retentionfactor

My answer of "the double root" (2*sqrt(N)) was deemed incorrect.
Anyone of how i've done wrong?
