Question
Which of the following is not a polynomial?
Answer: Option C
:
C
All the variables of a polynomialshould have whole numbers asexponents.
Forx+x2,the exponents of thevariable x are 1 and 2. All theexponents are whole numbers.Therefore, it is a polynomial.
In the expression3√y+y2,exponentof3√yis13,but13is not a wholenumber.Hence,3√y+y2is not a polynomial.
Forx+√3,the exponent of thevariable is 1which is a whole number.Therefore, it is a polynomial.
For x,the exponentof the variable is1 which is a whole number.Therefore, it is a polynomial.
