    Answer: (3) – 126

    Explanation:-
    Given-
    m = -4  &  n = -2

    Then, the value of   m3 – 3m2 + 3m + 3n + 3n2 + n3
    Put the value of m = -4  & n = -2
    Then, (-4)3 – 3(-4)2 + 3 (-4) + 3 (-2) + 3(-2)2 + (-2)3
    = – 64 – 3(16) – 12 – 6 + 3(4) – 8
    = -64 – 48 – 18 + 12 – 8
    = -138 + 12
    = – 126

    Hence, the answer is (3) – 126.
