Answer:
[tex]5 \sqrt{3} - 20 \sqrt{2} [/tex]
Step-by-step explanation:
[tex]simpify \\ \sqrt{75} - 4 \sqrt{8} - 3 \sqrt{32} \\ from \: the \: above \: get \: two \: numbers \: \\ such \: that \: when \: multiplied \: gives \\ \: the \: numbers \: inside \: the \: root \\ and \: one \: of \: the \: numers \: should \\ be \: a \: perfect \: square. \\ \sqrt{25 \times 3} - 4 \sqrt{4 \times 2} - 3\sqrt{16 \times 2} \\ 5 \sqrt{3} - 4 \times 2 \sqrt{2} -3 \times 4\sqrt{2} \\ 5 \sqrt{3} - 8 \sqrt{2} - 12\sqrt{2} \\ 5 \sqrt{3} - 20 \sqrt{2} [/tex]
