What is the degree of the polynomial (8y^6-5y^3+14)?
Answer and explanation
Correct answer: 6
The degree of a polynomial is the greatest exponent of its variable in a term with a non-zero coefficient. Here, the powers of y are 6, 3, and 0, so the greatest power is 6. Therefore, the correct answer is 6. The number 14 is a constant term and has degree 0, so it is not the degree of the polynomial. Exam tip: To find the degree, look for the highest power of the variable, not the coefficient.
