MCQ
Which of the following is a polynomial?
- A$\sqrt[3]{\text{y}}+4$
- B$\sqrt{\text{y}}-3$
- ✓$\text{y}$
- D$\frac{1}{\sqrt{\text{y}}}+7$
✓
Answer
Correct option: C.
$\text{y}$
A polynomial is an algebraic expression in which the variables involved have only non-negative integrals powers.
Option $(a)$, $(b)$ and $(d)$ have negative and non-integral powers,
So they are not polynomials.
