Zad 4
[tex] \sqrt{36 \times 64} = 6 \times 8 = 48[/tex]
[tex] \sqrt{36 + 64} = \sqrt{36} + \sqrt{64} = 6 + 8 = 14[/tex]
[tex] \sqrt{27} \times \sqrt{3} = \sqrt{27 \times 3} = \sqrt{81} = 9[/tex]
[tex] \sqrt{17} \times \sqrt{17} = \sqrt{17 \times 17} = \sqrt{289} = 17[/tex]
Zad 6
[tex]2 \sqrt{3} = 2 \times \sqrt{3} = \sqrt{4} \times \sqrt{3} = \sqrt{4 \times 3} = \sqrt{12} [/tex]
[tex]2 = \sqrt{4} [/tex]
[tex]5 \sqrt{3} = 5 \times \sqrt{3} = \sqrt{25} \times \sqrt{3} = \sqrt{25 \times 3} = \sqrt{75} [/tex]
[tex]5 = \sqrt{25} [/tex]
[tex]3 \sqrt{5} = 3 \times \sqrt{5} = \sqrt{9} \times \sqrt{3} = \sqrt{3 \times 9} = \sqrt{27} [/tex]
[tex]3 = \sqrt{9} [/tex]
