Question

determine the degree of the polynomial.
$2a^8 + 3a - 9$
the degree of the polynomial is \boxed{}.

Explanation:

Step1: Recall polynomial degree

The degree of a polynomial is the highest power (exponent) of the variable in the polynomial.

Step2: Identify exponents

In the polynomial \(2a^{8}+3a - 9\), the terms have exponents: for \(2a^{8}\), exponent is 8; for \(3a\), exponent is 1; for \(-9\), exponent is 0.

Step3: Determine highest exponent

The highest exponent among 8, 1, and 0 is 8.

Answer:

8
