Răspuns:
a) x = -2
b) x = 4
c) [tex]x = \frac{5}{3}[/tex]
Explicație pas cu pas:
a)
[tex]\sqrt{6} x + \sqrt{24} = 0[/tex]
[tex]\sqrt{6} x = -\sqrt{24}[/tex]
[tex]x = \frac{-\sqrt{24} }{\sqrt{6} } = -\sqrt{\frac{24}{6} } = -\sqrt{4} = -2[/tex]
b)
[tex]\sqrt{5} x - \sqrt{80} = 0[/tex]
[tex]\sqrt{5} x = \sqrt{80}[/tex]
[tex]x = \frac{\sqrt{80} }{\sqrt{5} } = \sqrt{\frac{80}{5} } = \sqrt{16} = 4[/tex]
c)
[tex]3\sqrt{3} x = \sqrt{75}[/tex]
[tex]x = \frac{\sqrt{75} }{3\sqrt{3} } = \frac{\sqrt{25*3} }{3\sqrt{3} } = \frac{5\sqrt{3} }{3\sqrt{3} } = \frac{5}{3}[/tex]
