Question
Which of the following is a polynomial?
Options
`x/y`
`x^(sqrt2) - 3x`
`x^(-2) + 7`
`sqrt2 x^2 + 1/2`
Solution
`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.
