⟹$\frac{2tan30}{1 + {tan}^{2}30 }$

$⟹ \frac{2 \times \frac{1}{ \sqrt{3} } }{1 + ( { \frac{1}{ \sqrt{3} }) }^{2} } </p><p>$

$⟹</p><p> \frac{ \frac{2}{ \sqrt{3} } }{1 + \frac{1}{3} }$

$⟹</p><p> \frac{ \frac{2}{ \sqrt{3} } }{ \frac{4}{3} } = \frac{2}{ \sqrt{3} } \times \frac{3}{4}$

$⟹ \frac{2}{ \sqrt{3} } \times \frac{ \sqrt{3} \times \sqrt{3} }{4} = \frac{2 \sqrt{3} }{4} = \frac{ \sqrt{3} }{2} </p><p>$

Hence proved

Answer 2

Answer:

$2 \times 30 = 60$

$2 \div 30 = 0.06$

$2 + 30 = 32$

$2 - 30 = - 28$
