Explicație pas cu pas:
a=[tex]a=\frac{10}{\sqrt{5} } +\frac{5}{\sqrt{10} } -\sqrt{20} =\frac{10\sqrt{5} }{5} +\frac{5\sqrt{10} }{10} -\sqrt{20} =2\sqrt{5} +\frac{\sqrt{10} }{2} -2\sqrt{5} =\frac{\sqrt{10} }{2}[/tex]
b=[tex]\sqrt{24} +\sqrt{40} -2\sqrt{6} =2\sqrt{6} +4\sqrt{10} -2\sqrt{6} =4\sqrt{10}[/tex]
mg=[tex]\sqrt{a*b} =\sqrt{\frac{\sqrt{10} } {2}*4\sqrt{10} }=\sqrt{2*10} =2\sqrt{5}[/tex]
