Question
Which one of the following is a polynomial?
✓
Answer
$\text{x}^2+\frac{3\text{x}^{\frac{3}{2}}}{\sqrt{\text{x}}}$ Solution: Since the power of the variable of all terms of a polynomial should be a whole number. Then $\text{x}^2+\frac{3\text{x}^{\frac{3}{2}}}{\sqrt{x}}$ $=\text{x}^2+3\text{x}^{\frac{3}{2}-\frac{1}{2}}$ $=\text{x}^2+3\text{x}^{\frac{2}{2}}$ $=\text{x}^2+3\text{x}$ Here the powers of variable are whole number. therefore the given expression is a polynomial.
