# How many variable terms are in the expression 3x^{3}y + 5x^{2} + y + 9?

**Solution:**

The given expression is

3x^{3}y + 5x^{2} + y + 9

A letter represents a variable in the expression.

Let us check for each term for the variables.

In the first term 3x^{3}y, x^{3}y is the variable

In the second term 5x^{2}, x^{2} is the variable

In the third term y, y is the variable

In the last term 9, there is no variable

So in the expression, x^{3}y, x^{2} and y is the variable.

Therefore, the variable terms are x^{3}y, x^{2} and y are the variables.

## How many variable terms are in the expression 3x^{3}y + 5x^{2} + y + 9?

**Summary:**

The variable terms in the expression 3x^{3}y + 5x^{2} + y + 9 are x^{3}y, x^{2} and y.
