ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions.

Correct option: Third one

Step-by-step explanation:

A polynomial is an expression in the form:

Where n is a non-negative integer number, and a, b, ... are real coefficients.

The first option is not a polynomial, because there is a non-integer number (5/2) in the exponent of y.

The second option is not a polynomial, because there is a negative integer number in the exponent (the fraction is the same as , and is the same as ).

The third option is a polynomial, because all numbers in exponent are non-negative integers.

The fourth option is not a polynomial, because there is a variable x in the exponent, so we don't know if the exponent is a non-negative integer number.
