State whether a given pair of terms is of like or unlike terms. (i) `1100` (ii) `-7x, 5/2x` (iii) `-29x , 29y` (iv) `14xy, 42yx`

Explanation

To determine whether each pair of terms is made up of like or unlike terms, we need to analyze the variables present in each term. Like terms are those that have the same variables raised to the same powers, while unlike terms have different variables or different powers.

Let's go through each part step by step:

### Step 1: Analyze the first pair of terms
**Terms:** \( 1100 \) and \( 100 \)

- Both terms are constants and do not have any variables.
