Answer:
Explanation:
It looks like you want to find the base of the expression "4z^3." In this expression, "4" is the coefficient, and "z^3" is the variable part. The base of the expression is the variable part, which is "z^3."
The base is "z," and the exponent is "3." So, the expression "4z^3" is a term with a base of "z" and an exponent of 3.
