Answer:
The variable in the expression n^2 6n*3 is **n**.
Here's why:
* An **expression** in mathematics combines numbers, variables, and operations like addition, subtraction, multiplication, and exponentiation.
* A **variable** is a symbol that represents an unknown or changing value. In this case, the letter "n" is used consistently throughout the expression.
* The ^ symbol denotes **exponentiation**. n^2 means "n to the power of 2," which signifies n multiplied by itself twice.
* The number 6 is a **coefficient**. It multiplies the variable n.
* The number 3 is also a coefficient, multiplying the product of 6 and n (6n).
Since "n" appears in all the terms and is not a coefficient or an exponent of another variable, it's the variable in the expression.
