Design a combinational logic circuit that will generate the square of all the combinations of a three bit binary number

 

It sounds more like the title of the thread should have been "Hi, Please answer this for me."

If you want *help*, then you have to provide us with YOUR attempt to solve YOUR homework problem. We can then see where you are going astray, if anywhere, as guide you back on track.

You can start by defining the problem you are trying to solve a bit better. What is a "combination of a three bit binary number"?

 

In addition to what WBahn said, what elements are you allowed to use to solve the problem? When I was asked this problem in school, it was using an EPROM, but it can be done the long way too...

 

Have you made a chart showing the inputs and outputs? If so, post it.
