Hello.part a5x + 3y^3 +2zi know it is in standard form because there are no more like terms.part bthe closure property with regards to polynomials states that polynomials are always closed under multiplication. the coefficients and the exponents can change unlike in addition and subtraction. the variables and coefficients also automatically fit in a polynomial.examplea*1 = aif a = 6, then 6*1=6this is an example of multiplication under polynomials.  have  a nice day
