An expression having one term is called a ........ .

Answer

To solve the question "An expression having one term is called a ........", we can follow these steps:

### Step 1: Understand the Definition
An expression in mathematics is a combination of numbers, variables, and operations. When we refer to an expression having one term, we are looking for a specific type of expression.

**Hint:** Think about how many parts or terms are in the expression.

### Step 2: Identify the Type of Expression
An expression that consists of only one term is known as a "monomial." This means it cannot be separated into different parts by addition or subtraction.

**Hint:** Recall the prefix "mono-" which means one.

### Step 3: Provide an Example
An example of a monomial is \(3x^2yz\). This expression has only one term and includes multiplication of constants and variables.

**Hint:** Try to think of other examples of monomials, such as \(5a\) or \(7xy^2\).

### Conclusion
Therefore, the answer to the question is: An expression having one term is called a **monomial**.
