Answer 1

Răspuns:

Media geometrica $m_{g}$ = $\sqrt{a*b}$

a) $m_{g}$ = $\sqrt{12*3}$= $\sqrt{36}$= 6

b) $m_{g}$ = $\sqrt{8*2}$= $\sqrt{16}$= 4

c) $m_{g}$ = $\sqrt{18*8\\}$= $\sqrt{144}$= 12

d) $m_{g}$ = $\sqrt{3\frac{1}{5}*5}$= $\sqrt{\frac{16}{5} *5}$= $\sqrt{16}$= 4

e) $m_{g}$ = $\sqrt{\frac{7}{12}*2\frac{1}{3} }$= $\sqrt{\frac{7}{12} *\frac{7}{3} }$= $\sqrt{\frac{49}{36} }$= $\frac{7}{6}$

f) $m_{g}$ = $\sqrt{\sqrt{5}^{-1} *\sqrt{\frac{5}{16} }$= $\sqrt{\sqrt{\frac{1}{5} } *\sqrt{ \frac{5}{16} }$= $\sqrt{\sqrt{\frac{1}{16} } }$= $\sqrt{\frac{1}{4} }$= $\frac{1}{2}$

Coroana? <3
