Answer 2

$\sqrt{3}$

Step-by-step explanation:

$Given, \: \: \: \: \frac{2tan30°}{1 - tan^{2}30° } \\ Now, \: \: \: \frac{2 (\frac{1}{ \sqrt{3} }) }{1 - ( \frac{1}{ \sqrt{3} } )^{2} } = \frac{ \frac{2}{ \sqrt{3} } }{ 1 - \frac{1}{3} } \\ = \frac{ \frac{2}{ \sqrt{3} } }{ \frac{2}{3} } = \frac{2}{ \sqrt{3} } \times \frac{ 3}{2} \\ = \sqrt{3} \\ \\ 2nd \: \: method: \: \: \: use \: \: this \\ \boxed{ \frac{2tan \theta}{1 - tan^{2} \theta } = tan2 \theta } \\ Now, \: \: \frac{2tan30°}{1 - tan^{2}30° } = tan2(30°) \\ = tan60° = \sqrt{3}$
