If n is an integer and 5^n > 4,000,000, what is the least possible value of n?	Choose one:	A) 7	B) 8	C) 9	D) 10	E) 11
When you separate the 4000000 into factors of 5 and 2 you get - &gt; 10^6 x 2^2 = 5^6 x 2^8   2 to the ^ 8 = 256 so its 256 x 5^6   that means 5^6 x 5^x must be greater   5^x &gt; 256   5^1=5   5^2=25   5^3= 125   5^4= 625 - &gt; so x must be at least 4   5^(6+4)= 5^10   ANSWER:10
<result>D</result>
