Question

How do you find the degree of `2a^2b^5+5-ab`?

Answer 1

7

Explanation:

If we consider `a` and `b` to be variables, the degree of a polynomial is the degree of the term with highest degree.

The polynomial `2a^2b^5 + 5 - ab` is composed by the factors:

• `2a^2b^5` has degree `7` (sum of the power of `a` and the power of `b`);
• `5` has degree `zero` (independent term);
• `-ab` has degree `2`.

By the previous, the degree of the polynomial is `7`.
