With respect to (y), what is the degree of (4x^7y^2-9x^5y^8+6y^3-1)?

Answer and explanation

Correct answer: 8

When the polynomial is considered with respect to \(y\), \(x\) is treated as a constant. The powers of \(y\) in the terms are \(2, 8, 3\), and \(0\), respectively. The greatest power is \(8\), occurring in \(-9x^5y^8\); hence the degree is \(8\). Option \(7\) is the highest power of \(x\), not the degree with respect to \(y\). Exam tip: for degree in one variable, compare powers of that variable only.
