What is the highest power in (4s^3-2s^2+s-8)?
Answer and explanation
Correct answer: 3
The powers of the variable s in the expression are 3, 2, and 1, while the constant term −8 has power 0. Therefore, the highest power is 3, found in the term 4s^3. The number 8 is only part of the constant term, not a power. Exam tip: To find the degree of a polynomial, identify the greatest exponent of its variable.
