The product of all the prime numbers less than 12 is closest to which of the following powers of 10?	Choices
A) a) 10^9  B) b) 10^8  C) c) 10^7  D) d) 10^3*2.31  E) e) 10^5
Group these numbers so as to get product close to a multiple of 10, so they can be rewritten as (2*5)(3*7)(11)= 10*21*11   Now take out power of 10 from each number and rewrite   10*10*10(1*2.1*1.1) or 10^3*(1*2.1*1.1) =2.31*10^3   d) 10^3*2.31
