If n is a positive integer and \(m = 6.2*10^n\), what is the value of m?
(1) \(6*10^3 < m < 5*10^5\)
(2) \(m^2 = 3.844*10^9\)
(1) \(6*10^3 < m < 5*10^5\)
(2) \(m^2 = 3.844*10^9\)

given \(m = 6.2*10^n\),
or say 62*10^n-1
#1
\(6*10^3 < m < 5*10^5\)
here from m = 62*10^n-1 value of n can be 3,4 ,5 insufficient
#2
\(m^2 = 3.844*10^9\)[/quote]
m^2= 3844*10^6
m= 62*10^3
sufficient
IMO B

Given:
1. n is a positive integer
2. \(m = 6.2*10^n\)
Asked: What is the value of m?
(1) \(6*10^3 < m < 5*10^5\)
m>6*10^3 = > m>6.2*10^2
m<5*10^5 = > m<6.2*10^5
m = 3 or 4
NOT SUFFICIENT
(2) \(m^2 = 3.844*10^9\)
m = \sqrt{38.44}*10^4
m = 6.2*10^4
SUFFICIENT
IMO B
