If k is a positive integer and n=7.049*10^k, what is the value of k?

(1) 7,500 < n < 75,000

(2) 10^4<n<10^5

Guys my approach

a) 1<n<10

1< 7.049 * 10^k<10

10^k=10^0 = 1(now my concern here is when it is mentioned that k is a positive integer it can be zero also)

1<7<10

Sufficient

b) 1<n<10

same put value of n you ill get k=0

Pls clarify the correct interpretation of k is positive integer
