## Computer Science: An Overview: Global Edition (12th Edition)

The Answer is : $No$
The Answer is $No$ because the largest value that can be stored in excess of eight notation is $(7)$, represented by $(1111)$. $To$ represent a larger value, at least an excess of $(16)$ (which uses patterns of 5 bits) must be used. $Similarly,$ $(6)$ cannot be represented in excess of four notation. (The largest value that can be represented in excess four notation is 3.)
