Answer of this question?

Dear Student.

$$\begin{gathered} Multiplying numerator and denominator by \sqrt{3} \\ \frac{2-\sqrt{3}}{\sqrt{3}}\times \frac{\sqrt{3}}{\sqrt{3}}=\frac{2\sqrt{3}-3}{3} \\ U\sin g \sqrt{3}=1.732: \\ \frac{2\times 1.732}{3}-\frac{3}{3} \\ =\frac{3.464}{3}-1 \\ =1.1546-1 \\ =0.1546 \end{gathered}$$

We hope that this answer solves your query.
