You guys give up yet?

misty1212 · Answer

so 
$$0.1\times 2^n=15,000,000,000$$ solve for $n$

misty1212 · Answer

or 
$$2^n=150,000,000,000$$ answer is 
$$\frac{\ln(150,000,000,000)}{\ln(2)}$$

The fold doubles every time you fold it, after 10 folds it's over 10 cm thick. SO after 42 folds, its around 439804 km thick, tall enough to reach the moon. :D
