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.
