For this case, we have the following polynomial: 
 

 A term of the polynomial composed by: 
 
, where: 
 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) 
 Thus, using the previous definition, it is observed that the expression has 5 terms.
