5z ^ 3 - 2z ^ 4 - 9z ^ 2 + z What is the degree of the polynomial ?
Mariulka [41]

Answer:

Step-by-step explanation:

For any polynomial, we can determine the degree by finding the variable with the largest exponent. For the given polynomial:

5z^{3} - 2z^{4} -9z^{2} + z

we can see that -2z^{4} contains the variable with the highest exponent, 4, so the degree of this polynomial is 4.
