Answer 1

Пошаговое объяснение:

2)

$8 \sqrt{75} = 8 \sqrt{25 \times 3} = 8 \times \sqrt{25} \times \sqrt{3} = 8 \times 5 \times \sqrt{3} = 40 \sqrt{5}$

3)

$\frac{5}{2} \sqrt{48} = \frac{5}{2} \sqrt{16} \times \sqrt{3} = \frac{5}{2} \times 4 \times \sqrt{3} = 10 \sqrt{3}$

4)

$5 \sqrt{3} + 3 \sqrt{4} \times \sqrt{3} = 5 \sqrt{3} + 6 \sqrt{3} = 11 \sqrt{3}$

5)

$5 \sqrt{9 \times 3} + 7 \sqrt{4 \times 3} = 5 \times 3 \times \sqrt{3} + 7 \times 2 \times \sqrt{3} = 29 \sqrt{3}$

6)

$2 \sqrt{16 \times 3} + \frac{1}{3} \sqrt{9 \times 3} = 2 \times 4 \times \sqrt{3} + \frac{1}{3} \times 3 \sqrt{3} = 9 \sqrt{3}$
