Объяснение:

4)

[tex] \frac{6}{ \sqrt{3} } = \frac{6}{ \sqrt{3} } \times \frac{ \sqrt{3} }{ \sqrt{3} } = \frac{6 \sqrt{3} }{3} = 2 \sqrt{3} [/tex]

6)

1.

[tex] \sqrt{ \frac{9}{4} } + \sqrt{3 + \sqrt{36} } = \frac{3}{2} + \sqrt{3 + 6} = 1.5 + \sqrt{9} = 1.5 + 3 = 4.5[/tex]

2.

[tex] \sqrt{45 \times 10} = \sqrt{9 \times 5 \times 2 \times 5} = 3 \times 5 \sqrt{2} = 15 \sqrt{2} [/tex]

3.

[tex] \sqrt{10} - \sqrt{40} = \sqrt{10} - \sqrt{4 \times 10} = \sqrt{10} - 2 \sqrt{10} = - \sqrt{10} [/tex]

4.

[tex] \sqrt{300} - \sqrt{75} = \sqrt{100 \times 3} - \sqrt{25 \times 3} = 10 \sqrt{3} - 5 \sqrt{3} = 5 \sqrt{3} [/tex]
