using the formula for an exponential function: 
y=b*a^x

Insert you values: 
y=200*2^x

b=200 because there are 200 bacteria in the beginning
a=2 because 200%/100%=2. (200 bacause it doubles)

Insert 20 in x and solve for y: 
y=200*2^13=819200

So after 12 hours there are 819200 bacteria. 

I hope that helped.
