What will be the degree of (3x^5+0x^7-2x+4)?

Answer and explanation

Correct answer: 5

The degree of a polynomial is the highest power of the variable among terms with non-zero coefficients. Here, 0x^7 is a zero term, so it does not contribute to the degree. Among the remaining terms, 3x^5 has the highest power; therefore, the degree is 5. Choosing 7 would be incorrect because the coefficient of x^7 is zero. Exam tip: Remove terms with zero coefficients before finding the degree.
