If \(n\) is an integer and \(\frac{1}{10^{n+1}} \lt 0.00737 \lt \frac{1}{10^n}\), then what is the value of \(n\)?
A. 1
B. 2
C. 3
D. 4
E. 5
We can plug in the values and solve this question
When it comes to plugging in, i generally pick the middle option (option 3)
when n = 3
1/10^(3+1) = 1/10^4 = 0.0001. This is not less than 0.007.
Now, lets consider n=2
1/10^3 = 0.001 and 1/10^2 = 0.01
0.001< 0.007<0.01
Hence, option B
