Question

Which of the following is a polynomial?

Options

• `x/y`

• `x^(sqrt2) - 3x`

• `x^(-2) + 7`

• `sqrt2 x^2 + 1/2`

Answer 1

`bb(sqrt2x^2+1/2)`

Explanation:

In an algebraic expression, if the powers of the variables are whole numbers then the algebraic expression is a polynomial.

In the expression `sqrt2 x^2 + 1/2`, the power of the variable x is 2, which is a whole number. So, the expression `sqrt2 x^2 + 1/2` is a polynomial.
