Answer» Which of the following expressions are polynomials? In case of a polynomial, write its degree. (i) $x^{5} - 2 x^{3} + x + \sqrt{3}$ (ii) $y^{3} + \sqrt{3} y$ (iii) $t^{2} - \frac{2}{5} t + \sqrt{5}$ (iv) $x^{100} - 1$ (v) $\frac{1}{\sqrt{2}} x^{2} - \sqrt{2} x + 2$ (vi) $x^{- 2} + 2 x^{- 1} + 3$ (vii) 1 (viii) $\frac{- 3}{5}$ (ix) $\frac{x^{2}}{2} - \frac{2}{x^{2}}$ (x) $\sqrt[3]{2} x^{2} - 8$ (xi) $\frac{1}{2 x^{2}}$ (xii) $\frac{1}{\sqrt{5}} x^{\frac{1}{2}} + 1$ (xiii) $\frac{3}{5} x^{2} - \frac{7}{3} x + 9$ (xiv) $x^{4} - x^{\frac{3}{2}} + x - 3$ (xv) $2 x^{3} + 3 x^{2} + \sqrt{x} - 1$
