a)
[tex]5\sqrt{3} = \sqrt{5^{2}\cdot3} = \sqrt{25\cdot3} = \sqrt{75}\\\\0,3\sqrt{5} = \sqrt{0,3^{2}\cdot5} = \sqrt{0,09\cdot5} = \sqrt{0,45}[/tex]
b)
[tex]\sqrt{300} = \sqrt{3}\cdot100} = \sqrt{3}\cdot\sqrt{100} = \sqrt{3}\cdot10 = 10\sqrt{3}\\\\\sqrt{32} = \sqrt{16\cdot2} = \sqrt{16}\cdot\sqrt{2} = 4\sqrt{2}[/tex]
