Resolution: V/2^n -1.
In the problem resolution is given r=5mV(5x10^-3), and we're to find the n-bit.
By equating the formula of resolution:
We Let x=n as a variable of unknown.
5*10^-3=5/2^x -1 ---> input in your calculator then shift solve for X then press = you can get 9.967 or approximately equal to 10.

How 1000 you take for calculation?

How can you say N = 9.96 something?

Resolution = Analog Input/Number of Steps.
Number of Steps = (2^N)-1.
Resolution = 5 m.
Analog Input = 5.
N = 9.96 something.
In terms of resolution always round off to higher number. So 10 the simplified explanation.
