Question

which of the following are not polynomials

Answer 1

Answer:

A, C, F.

Step-by-step explanation:

A polynomial consists of an expression that involves only non-negative integer exponents for the variable; in all of your cases, the variable is x.

So, expression A has a square root of x, that is a rational exponent.

Expression C has variables in the denominators, that is negative exponent.

Expression F has variable at the exponent.

Answer 2

Answer:

A, C and F.

Step-by-step explanation:

A is not a polynomial because it contains a square root.

C is not a polynomial because it contains division by a variable (7/2x).

F is not one also because  the variable is in the exponent (5^4x).
