The degree of p(x) $\times$ q(x) is the sum of their degrees according to the multiplication property of exponents.
According to the multiplication property of exponents $x^{m} \times x^{n} = x^{m+n}$ Therefore, the degree of $p(x) \times q(x)$ is the sum of their degrees according to the rule of the multiplication property of exponents.
