bentuk sederhana dari 5×√(8)+√(72)−√(98)−2×√(32)=........

[tex]5 \sqrt{8} + \sqrt{72 } - \sqrt{98} - 2 \sqrt{32} \\ = 5 \sqrt{4 \times 2} + \sqrt{36 \times 2} - \sqrt{49 \times 2} - 2 \sqrt{16 \times 2} \\ = 5 \times 2 \sqrt{2} + 6 \sqrt{2} - 7 \sqrt{2} - 2 \times 4 \sqrt{2} \\ = 10 \sqrt{2} + 6 \sqrt{2} - 7 \sqrt{2} - 8 \sqrt{2} \\ = \sqrt{2} [/tex]
