Which expression is NOT a polynomial?

Step-by-step explanation:

A rule for polynomials, is that if they have variables, the powers should be positive whole numbers. Basically, this means you cannot divide by a variable, but in option 4, second term, you are dividing 5 by x, which is the same as. This means you are not raising the variable to a positive power, which means the whole 4th option is not a polynomial.

the answer is. -82562234434584

step-by-step explanation:

both equations and proportions are better.
