Step-by-step explanation:

Definition of: Coefficient

A number used to multiply a variable.

Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.

Variables with no number have a coefficient of 1.

Example: x is really 1x.

coefficients:

3x⁴+ 5x² + 1x

sum of the coefficients:

3 + 5 + 1

8 + 1
