Answer:
L.H.S.
= (d ^ 2 * k ^ 6 + d ^ 2 * k ^ 4 + d ^ 2 * k ^ 2)(d ^ 2 * k ^ 4 + d ^ 2 * k ^ 2 + d ^ 2) = d ^ 2 * k ^ 2 * (k ^ 4 + k ^ 2 + 1) * d ^ 2 * (k ^ 4 + k ^ 2 + 1)
= d ^ 4 * k ^ 2 * (k ^ 4 + k ^ 2 + 1) ^ 2
R.H.S.
=( ab + bc +cd)^ 2
=( d * k ^ 3 * d * k ^ 2 +dk^ 2* dk+dk* d)^ 2
= d ^ 4 * k ^ 2 * (k ^ 4 + k ^ 2 + 1) ^ 2
L .H.S.=R.H.S
Hence proved.
