Question

Calculati media aritmetica si media geometrica a numerelor:
a=radical 48
b=radical 12
repede va rog multt!! dau coroana!!

Answer 1

Răspuns:

Explicație pas cu pas:

Media aritmetica :( $\sqrt{48}$+$\sqrt{12}$) :2= (4$\sqrt{3}$+2$\sqrt{3}$) :2= 6$\sqrt{3}$:2= 3$\sqrt{3}$

$\sqrt{48}$=4$\sqrt{3}$

$\sqrt{12}$=2$\sqrt{3}$

Media geometrica = $\sqrt{4\sqrt{3} * 2\sqrt{3} }$= $\sqrt{24}$=2$\sqrt{6}$
