Question

Calculati media aritmetica si media geometrica a numerelor: x=√2-1 si y=√2+1. Urgeent!! Dau coronita

Answer 1

$x= \sqrt{2} -1 \\ y= \sqrt{2} +1 \\ m_g= \sqrt{( \sqrt{2} -1)( \sqrt{2} +1)} = \sqrt{2-1} = \sqrt{1} =1 \\ m_a= \frac{ \sqrt{2} -1+ \sqrt{2} +1}{2} = \frac{2 \sqrt{2} }{2} = \sqrt{2}$
