Question

√3 •tan60-tan30/1+tan 60•tan 30=1

Answer 1

$\sqrt{3} \times \frac{ \tan(60) - \tan(30) }{1 + \tan(60) \tan(30) } \\ = \sqrt{3} \times \frac{ \sqrt{3} - \frac{1}{ \sqrt{3} } }{1 + \sqrt{3} \times \frac{1}{ \sqrt{3} } } \\ = \sqrt{3} \times \frac{ \frac{3 - 1}{ \sqrt{3} } }{1 + 1} \\ = \frac{2}{2} \\ = 1 \: = rhs\: (proved)$
