For this case, we have the following expression:
![3x ^ 6yz + x ^ 4y ^ 2 + 2xz ^ 5-6x ^ 2y ^ 3-7y\\](https://img.qammunity.org/2019/formulas/mathematics/middle-school/7s539lwhislm2ry33ovmv7ylea3zmsbai2.png)
Where for example, 3x ^ 6yz represents a polynomial term that consists of:
3: Represents the coefficient of the term
x, y, z: Represent the associated variables
6: Represents the exponent associated with the variable x. (y, z have exponent 1)
Therefore, the expression has 5 terms.
