What is the degree of (x^5(x-4)^2)?

Answer and explanation

Correct answer: 7

The degree of \(x^5\) is 5, and the degree of \((x-4)^2\) is 2. The degree of the product of two non-zero polynomials equals the sum of their degrees. Therefore, the degree is \(5+2=7\). Option 10 is incorrect because the degrees are not multiplied. Exam tip: In a product, add the degrees; for a power of a factor, multiply its degree by the power.
