Answer:
11
Explanation:
The degree of a term is the sum of the powers of its variables. The degree of the polynomial is the largest of the degrees of its terms.
5a^6bc^2 -- degree = 6 +1 +2 = 9
8d^5 -- degree = 5
7e^6f^2 -- degree = 6 +2 = 8
-10g^4h^7 -- degree = 4 +7 = 11
The largest of the degrees, {9, 5, 8, 11}, is 11.
The degree of the polynomial is 11.
