Answer 2

Explicație pas cu pas:

$9 \sqrt{3} - 2 \sqrt{3} + \sqrt{3} - 8 \sqrt{3} = 10 \sqrt{3} - 10 \sqrt{3} = 0$

$\sqrt{10} + 6 \sqrt{40} - 2 \sqrt{90} + \sqrt{3} = \sqrt{10} + 6 \sqrt{ {2}^{2} \cdot 10} - 2 \sqrt{ {3}^{2} \cdot 10} + \sqrt{3} = \sqrt{10} + 12 \sqrt{10} - 6 \sqrt{10} + \sqrt{3} = 13 \sqrt{10} - 6 \sqrt{10} + \sqrt{3} = 7 \sqrt{10} + \sqrt{3}$

$6 \sqrt[3]{2} + \sqrt[3]{2} - \sqrt[3]{5} - 7 \sqrt[3]{5} = 7 \sqrt[3]{2} - 8 \sqrt[3]{5}$

$\sqrt{7} + 3 \sqrt{28} - \sqrt{49} + 6 \sqrt{63} = \sqrt{7} + 3 \sqrt{ {2}^{2} \cdot 7} - \sqrt{ {7}^{2} } + 6 \sqrt{ {3}^{2} \cdot 7} = \sqrt{7} + 6 \sqrt{7} - 7 + 18 \sqrt{7} = 25 \sqrt{7} - 7$
