Answer:
D. 5
Step-by-step explanation:
The degree of a polynomial is the number that the highest exponent is powered. If we were to expand this:
10x⁴ - 8x⁵
We see that our highest exponent is -8x⁵, so our degree is 5.
The degree of a polynomial is the term with the highest power.
Since x^n x x^m = x^m+n
-2x^2 • 4x^3 = -8x^5
So D. 5
Since x^n x x^m = x^m+n
-2x^2 • 4x^3 = -8x^5
So D. 5
