Question

Write down the degree of the following polynomial:

$7x^3-5x^3{y}^2+4y^4-9$

• A. 3
• B. 4
• C. 5
• D. 1

Answer 1

The correct option is C 5

The degree of each of the polynomial $7x^3-5x^3{y}^2+4y^4-9$ is $5$.

The degree of a polynomial is the highest degree of its monomials (individual terms) with non-zero coefficients. The degree of a term is the sum of the exponents of the variables that appear in it, and thus is a non-negative integer.
