Question

Which algebraic expression is a polynomial with a degree of 3?

4x^ 3
2y^3 + 5y^2 – 5y
3y^3√4y
–xy√6

Answer 1

It would be the second choice. This expression is a polynomial because it is multiple terms and is a degree of three because the largest exponent is three. So your answer is:
2y^3 + 5y^2 - 5y
