1.
[tex]3 \sqrt{9} - 8 \sqrt{3} + 4 \sqrt{3} - \sqrt{12} = 3 \times 3 - 8 \sqrt{3} + 4 \sqrt{3} - \sqrt{4 \times 3} = 9 - 8 \sqrt{3} + 4 \sqrt{3} - 2 \sqrt{3} = 9 - 10 \sqrt{3} [/tex]
2.
[tex]6 \sqrt{2} = \sqrt{36 \times 2} = \sqrt{72} [/tex]
[tex]0.2 \sqrt{2} = \sqrt{0.04 \times 2} = \sqrt{0.08} [/tex]
3.
[tex] \sqrt{500} = \sqrt{100 \times 5} = 10 \sqrt{5} [/tex]
[tex] \sqrt{75} = \sqrt{25 \times 3} = 5 \sqrt{3} [/tex]
Myślę że pomogłem ;)
