Answer:
c. 2^32 times as many values can be represented.
Explanation:
For 32 bit integers, there are [tex]2^{32}[/tex] possible values.
For 64 bit integers, there are [tex]2^{64}[/tex] possible values, or [tex]\frac{2^{64}}{2^{32}} = 2^{32}[/tex] more values being represented.
So the correct answer is:
c. 2^32 times as many values can be represented.
