SUMMARY

The discussion centers around the validity of the term 5^x in a polynomial. It is established that 5^x is not a valid term in a polynomial due to the definition of polynomials, which only include terms with non-negative integer exponents. The conversation also touches on the nature of rational functions, defined as the quotient of two polynomial functions, further clarifying the distinction between polynomial terms and other mathematical expressions.

It is not.

A rational function is defined as the quotient of two polynomials functions. Like you said, 5x is not a valid term of a polynomial.

gb7nash,

there is no "like you said," because the OP didn't state that 5^x isn't
a valid term of a poynomial. He asked if it was.

...and gb7nash answered him. Is this really something to nitpick about?
