Answer:
- The constant in the expression is '8'.
Explanation:
The constant is a number with no variable multiplied with the constant.
- In this expression, 7k has a variable 'k', which is not a constant.
- If we look at 8, we can tell that it has no variable multiplied. This is a constant.
- When we look at the 2lk and 3l, they both have variables 'lk' and 'l' respectively. They are not constants.
Hence, the constant in the expression is '8'.
