Consider the following polynomial expression: 4x^5-16x^2+13x^8. Part B: What is the degree of the polynomial
Tanya [424]

Answer:

8

Step-by-step explanation:

Step 1: Write polynomial

4x⁵ - 16x² + 13x⁸

Step 2: Rearrange

13x⁸ + 4x⁵ - 16x²

The degree of a polynomial is the highest power. In this case, our degree would be 8 because of the x⁸ term being the largest exponent.
