Identify the terms, their coefficients for each of the following expressions: `3x^2y^2-5x^2y^2z^2+z^2` (ii) `9-a b+b c-c a`

Explanation

To identify the terms and their coefficients for the given expressions, we will break down each expression step by step.

### Part (i): Expression `3x^2y^2 - 5x^2y^2z^2 + z^2`

1. **Identify the terms**:
- The expression consists of three parts:
- The first term is `3x^2y^2`
- The second term is `-5x^2y^2z^2`
