\(2^n*2,000\geq{1,000,000}\);
\(2^n\geq{500}\);
\(n=9\) (since 2^9=512).

Hi All,
Certain questions on Test Day can be solved rather quickly with "brute force" - you don't need to be a genius and you don't need to have an 'elegant' approach....you just need to put pen to pad and do a bit of basic math.
Here, we're told that the population DOUBLES every year. We're asked APPROXIMATELY how many years it takes to go from 2,000 to 1,000,000+....
Start: 2,000
Yr. 1: 4,000
Yr. 2: 8,000
Yr. 3: 16,000
Yr. 4: 32,000
Yr. 5: 64,000
Yr. 6: 128,000
Yr. 7: 256,000
Yr. 8: 512,000
Yr. 9: 1,024,000
So, approximately 9 years have to pass to get to 1,000,000+.
GMAT assassins aren't born, they're made,
Rich
