    Có $\frac{1}{2\sqrt{3} }$

    = $\frac{1.\sqrt{3}}{2\sqrt{3}.$\sqrt{3}}$

    = $\frac{\sqrt{3}$}{6}$

    Chúc bạn học tốt ~

    `1/{2sqrt(3)} = sqrt(3)/6`

    `VT=1/{2sqrt(3)}={1.sqrt(3)}/{2.sqrt(3).sqrt(3)}=sqrt(3)/{2.(sqrt(3))^2}=sqrt(3)/{2.3}=sqrt(3)/6=VP` (đpcm)

    Vậy đẳng thức trên luôn đúng
