Formula mediei geometrice [tex]\boxed{Mg = \sqrt{a*b} }[/tex]
a) [tex]Mg = \sqrt{2*18} =\sqrt{36}=\sqrt{6^2} =6[/tex]
b) [tex]Mg = \sqrt{3*12}=\sqrt{36}=6\\[/tex]
c) [tex]Mg=\sqrt{\frac{14}{5}*\frac{10}{7} }=\sqrt{2*2 }=\sqrt{4} =2[/tex]
d) [tex]Mg = \sqrt{112*\frac{4}{7}}=\sqrt{16*4} =\sqrt{64}=8[/tex]
e) [tex]Mg = \sqrt{1,2*3,(3) }=\sqrt{\frac{12}{10}*\frac{33-3}{9} }=\sqrt{\frac{6}{5} *\frac{30}{9} }=\sqrt{\frac{6}{5} *\frac{10}{3} } =\sqrt{2*2} =\sqrt{4} =2[/tex]
