Which of the following expressions are polynomials in one variable and which are not ? State reasons for your answer. $3 \sqrt{t}+t \sqrt{2}$
Which of the following expressions are polynomials in one variable and which are not ? State reasons for your answer. $3 \sqrt{t}+t \sqrt{2}$
$3 \sqrt{t}+t \sqrt{2}$
$\Rightarrow 3 t^{1 / 2}+\sqrt{2} \cdot t$
$\because $ $\frac{1}{2}$ is not a whole number,
$\therefore $ $3 t^{1 / 2}+\sqrt{2} \cdot t,$ i.e. $3 \sqrt{t}+t \cdot \sqrt{2}$ is not a polynomial.
