media geometrica a nr. 2 radical de 8 si 3 radical de 2 este egala cu.........

Răspuns :

[tex]3 \sqrt{8} = 3 * 2 \sqrt{2} = 6 \sqrt{2} [/tex]

[tex]mg = \sqrt{a*b} [/tex]

[tex]mg = \sqrt{6 \sqrt{2} * 3 \sqrt{2} } [/tex]

[tex]mg = \sqrt{6*3*2} [/tex]

[tex]mg = \sqrt{36} [/tex]

mg=6
[tex]m_g=\sqrt{2\sqrt8\cdot3\sqrt2}=\sqrt{2\cdot3\sqrt{8\cdot2}}=\sqrt{6\cdot4}=2\sqrt6[/tex]
