Question

Calculati media geometrica a numerelor a si b , unde :
a=
$\sqrt{45}$
b=
$\sqrt{125}$
.
Rezolvare va rog​

Answer 1

$\it a=\sqrt{45}=\sqrt{9\cdot5}=3\sqrt5\\ \\ b=\sqrt{125}=\sqrt{25\cdot5}=5\sqrt5\\ \\ m_g=\sqrt{a\cdot b}=\sqrt{3\sqrt5\cdot5\sqrt5}=\sqrt{3\cdot5\cdot5}=\sqrt{25\cdot3}=5\sqrt3$
