    L.H.S=tan 6 ° tan 42 ° tan 66 °   tan 78 °
    now ,

    Use Trigonometric Identity  

    tanx * tan(60° - x) * tan(60° + x) = tan(3x)  

    set x = 6  

    tan6°   tan54°   tan66° = tan18° .................... ((1))  

    Similarly, set x = 18°  

    tan18°   tan42°   tan78° = tan54° ...................... ((2))  

    ((1)) * ((2)):  

    tan6° * tan54° * tan66° * tan18° * tan42° * tan78° = tan18° * tan54°  

    tan6° * tan66° * tan42° * tan78° = 1
    Hence
    L.H.S=R.H.S
