Answer:


( \sqrt[4]{7} + 2)( \sqrt[4]{7} - 2)( \sqrt[4]{7} + 4) \\ (first \: two \: is \: in \: the \: form \: of \: (x + y)(x - y) = {x}^(2) - {y}^(?) \\ then { \sqrt[4]{7} }^(2) - {2}^(2) \\ =( √(7) - 4) \\ so \: ( √(7) - 4)( √(7) + 4) \\ = { √(7) }^(2) - {4}^(2) \\ = 7 - 16 \\ = - 9 \\ thank \: you
