Specify the variables and the terms in the following algebraic expressions.
`13ab +2c`

Answer

To solve the question, we need to identify the variables and the terms in the given algebraic expression: `13ab + 2c`.

### Step-by-Step Solution:

1. **Identify the Expression**: The given algebraic expression is `13ab + 2c`.

2. **Define Variables**:
- Variables are symbols that represent numbers and can change or vary. In this expression, we can see the letters `a`, `b`, and `c` are present.
- Therefore, the variables in the expression are:
- **a**
- **b**
- **c**

3. **Identify the Terms**:
- Terms are the parts of the expression that are separated by addition or subtraction. In this case, the expression `13ab + 2c` has two parts:
- The first term is `13ab`.
- The second term is `2c`.
- Thus, the terms in the expression are:
- **13ab**
- **2c**

### Final Answer:
- **Variables**: a, b, c
- **Terms**: 13ab, 2c
