Answer:
only (2) and (4) are polynomial out of given options.
Step-by-step explanation:
Polynomial is an expression having variables having positive integer exponents with real constant coefficients. example
We are given some polynomials and we have to choose whether are polynomial or not.
Consider ,
1)
Since, Polynomial does not have a fractional exponent.
So, 1) Not a polynomial.
2)
Since all of the variables have integer exponents that are positive this is a polynomial.
3)
Not a polynomial because a term has a negative exponent .
4)
Since all of the variables have integer exponents that are positive this is a polynomial.
Thus, only (2) and (4) are polynomial out of given options.
