Is 4m^3x^2 a polynomial

A polynomial can have:

constants (like 3, −20, or ½)

variables (like x and y)

exponents (like the 2 in y2), but only 0, 1, 2, 3, etc. are allowed

that can be combined using addition, subtraction, multiplication and division  except  not division by a variable (so something like 2/x is right out)

So, a polynomial can have constants, variables and exponents,

but never division by a variable.

Also they can have one or more terms, but not an infinite number of terms.
