16.* 1 + a2 + a4
21. 3a2 + 1 - 3a – a3
19.* - x4 - 4a4
7.* x4 + 4 y4

What are the instructions for the problems? Simplify? Combine like terms? Factor?

What is the meaning of your "star" notation? What operation is being indicated by this?

Thank you! (Wink)

There are numerous problems with the way you have posted these questions. Some have already been mentioned. Another problem is the following:

Are we expected to assume that 3a has a different meaning to a3? Are we meant to assume that by a3 you mean a^3 etc.

If you want to get effective help in a timely manner, please post your questions clearly using standard notation and appropriate formatting. Showing the work you've done and answers that you got will also assist people in giving the help that is required.
