Question

plz answer this as soon as possible​

Answer 1

LHS=

$\frac{2 \: tan30}{1 - {tan30}^{2} }$

=

$\frac{2}{ \sqrt{3} } \div (1 - {( \frac{1}{ \sqrt{3} })}^{2})$

=

$\frac{2}{ \sqrt{3} } \div \frac{2}{3}$

=

$\frac{2}{ \sqrt{3} } \times \frac{3}{2}$

=

$\frac{3}{ \sqrt{3} }$

=

$\sqrt{3}$

=RHS

THEREFORE LHS=RHS
