What is the degree of the polynomial ((x^3-2)^3)?

Answer and explanation

Correct answer: 9

In \((x^3-2)^3\), the term with the highest power is \((x^3)^3=x^9\). Therefore, the highest exponent in the polynomial is 9, so its degree is 9. Option 6 is incorrect because the exponents are multiplied here: \(3\times3\), not added. Exam tip: To find the degree of a polynomial, identify the term with the greatest exponent after expansion or simplification.
