In this case, we'll have to carry out several steps to find the solution.
Step 01:
We must analyze the expressions to find the solution.
Step 02:
polynomial or not a polynomial
1. expression ===> not a polynomial
2. expression ===> not a polynomial
3. expression ===> not a polynomial
4. expression ===> polynomial
5. expression ===> not a polynomial
6. expression ===> not a polynomial
That is the full solution.
