bentuk sederhana dari √8+√75-(√32+√243) adalah?

[tex] \sqrt{8} + \sqrt{75} - (\sqrt{32} + \sqrt{243})\\= \sqrt{4.2} + \sqrt{25.3} - ( \sqrt{16.2} + \sqrt{81.3})\\ = 2 \sqrt{2} + 5\sqrt{3} - (4 \sqrt{2} + 9\sqrt{3})\\= 2 \sqrt{2} + 5 \sqrt{3} - 4 \sqrt{2} - 9 \sqrt{3}\\= -2 \sqrt{2} - 4 \sqrt{3} [/tex]
