1. [tex]\sqrt{3} + \sqrt{12} = \sqrt{3} + 2\sqrt{3} = 3\sqrt{3}[/tex]
2. [tex]\sqrt{54} - \sqrt{6} = 3\sqrt{6} - \sqrt{6} = 2\sqrt{6}[/tex]
3. [tex]\sqrt{50} - \sqrt{2} = 5\sqrt{2} - \sqrt{2} = 4\sqrt{2}[/tex]
4. [tex]\sqrt{10} + \sqrt{90} = \sqrt{10} + 3\sqrt{10} = 4\sqrt{10}[/tex]
5. [tex]\sqrt{28} - \sqrt{7} = 2\sqrt{7} - \sqrt{7} = \sqrt{7}[/tex]
6. [tex]\sqrt{45} + \sqrt{7} = 3\sqrt{5} + \sqrt{7}[/tex]
Nie jestem 100% pewna co do 6 przykładu, ale reszta jest dobrze :)
