well calculate all of them you know the second one would be like way to much it comes to over a million so that one is out 
then if that one out then you know that the last one cant be it because it comes to like negative a million so that leave the first and third 
the third is 10^2 which is really 10 times 10 so thats like saying the penicil is 100 pounds so what do you think the resonable guess would be?
