Step-by-step explanation:
The expression given in the question is 3n
This implies that 3 x n
The operator that exist between the coefficient and the variable is the multiplication operator
Where 3 is the coefficent and n = variable
This expression can be translated in the following ways
1. a product of 3 and a number n
2. 3 multiply by a number n
3. 3 times a number n
