The product of all the prime numbers less than 25 is closest to which of the following powers of 10? Choose one:	A) a) 10^9	B) b) 10^8	C) c) 10^8*2.23	D) d) 10^6	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*19)(13*17)*23 or 10*21*209*221* 23   Now take out power of 10 from each number and rewrite   10*10*100*100*10 (1*2.1*2.09*2.21*2.3) or 10^7*(1*2.1*2.09*2.21*2.3)=10^7*10*2.23   =2.23*10^8   c) 10^8*2.23
