[tex]21 \sqrt{150} + 2 \sqrt{3} (3 \sqrt{12 } - 50) - (2 \sqrt{18} - 48) = [/tex]

[tex] = 150 \sqrt{6} + 2 \sqrt{3} (3 \sqrt{12} - 50) - (2 \sqrt{18} - 48 = [/tex]

[tex] = 105 \sqrt{6} + 2 \sqrt{3} (6 \sqrt{3} - 50) - (2 \sqrt{18} - 48) = [/tex]

[tex] = 105 \sqrt{6} + 2 \sqrt{3} (6 \sqrt{3} - 50) - (6 \sqrt{2} - 48) = [/tex]

[tex] = 105 \sqrt{6} + 36 - 100 \sqrt{3} - (6 \sqrt{2} - 48) = [/tex]

[tex] = 105 \sqrt{6} + 36 - 100 \sqrt{3} - 6 \sqrt{2} + 48 = [/tex]

[tex] = 105 \sqrt{6} + 84 - 100 \sqrt{3} - 6 \sqrt{2} [/tex]
