Witam.
Zad 1
[tex]a) \: \sqrt{121} + \sqrt{49} - \sqrt{225} = 11 + 7 - 15 = 18 - 15 = 3[/tex]
[tex]b) \: \sqrt{196} - \sqrt{169} - \sqrt{144} = 14 - 13 - 12 = 1 - 12 = - 11[/tex]
[tex]c) \: \sqrt{0.25} + \sqrt{1.44} + \sqrt{6.25} = 0.5 + 1.2 + 2.5 = 1.7 + 2.5 = 4.2[/tex]
Zad 4
[tex]c) \: \sqrt{48} = \sqrt{16} \times \sqrt{3 } = 4 \sqrt{3} [/tex]
[tex]d) \: \sqrt{96} = \sqrt{16} \times \sqrt{6} = 4 \sqrt{6} [/tex]
[tex]e) \: \sqrt{108} = \sqrt{36} \times \sqrt{3 } = 6 \sqrt{3} [/tex]
Pozdrawiam,
Michał
