    For your report to the class, start by stating the conditions of polynomials:

    1)  Literal coefficients (the variable and its exponents) do not have negative exponents.   
    Example of expression with negative exponents:   
    3x⁻⁵  (properly written as 3/x⁵)
    3x³ - x⁻² + 5x    (properly written as 1/x²)
    (These examples are not polynomials)

    2⁻³   is a polynomial because it's a constant, not a coefficient. (2⁻³ is the same as 1/2³   or  1/8.)

    2.)  Literal coefficients do not have rational/fractional exponents.
    Examples with rational/fractional exponents:
    6x ^{ \frac{1}{2} }  (properly written as \sqrt{6x}

    3.)  No literal coefficients as denominators (because it's the same as condition number 1)
    Examples of variable/literal coefficient as a denominator:
     6/x²  (this is the same as 6x⁻²)

    4.) No literal coefficients/variables as radical expression (because it's the same as condition number 2).
    Examples of variables/literal coefficients as radical expression.

    \sqrt{7x}  (this radical expression is the same as (7x) ^{ \frac{1}{2} }

    The conditions enumerated above will be you basis/es for identifying a polynomial.

    1)  Not a polynomial because it has literal coefficients as denominators. They are 2x³  and  3x⁴.  (Check condition of polynomial #3)

    For the rest of the given expressions, just check the conditions of polynomials.
