Question

Which expressions are not polynomials?

A) 4x^(1/3)
B) 5 - 1/z
C) -ab²c
D) 2q - 1

Answer 1

The expressions that are not polynomials are 4x^(1/3), 5 - 1/z, and -ab²c. However, 2q - 1 is a polynomial.

Step-by-step explanation:

The expressions that are not polynomials are:

4x(1/3): This is not a polynomial because it contains a fractional exponent.

5 - 1/z: This is not a polynomial because it contains a variable in the denominator.

-ab²c: This is not a polynomial because it contains variables raised to a power.

On the other hand, 2q - 1 is a polynomial because it is a linear expression with integer exponents.
