Which of the foll

Answer :

Let us check for the option (a),


We have


We can write it as, x + 2x-1 + 3.


Here, x-1 is a polynomial.


x + 2x-1 + 3 is not a polynomial.


is not a polynomial.


For option (b),


We have


We can write it as, 3√x + 2x-1/2 + 5.


Here, x- 1/2 is not a polynomial.


3√x + 2x- 1/2 + 5 is not a polynomial.


is not a polynomial.


For option (c),


We have √2x2 - √3x + 6


Term-wise, √2 x2 is a polynomial


√3 x is a polynomial


6 is a polynomial


√2 x2 - √3 x + 6 is a polynomial.


For option (d),


We have x10 + y5 + 8.


Here, we have two variables, x and y.


Hence, it is clearly not a polynomial of single variable.


Thus, option (d) is correct.
