Question

calculati media aritmetica si geometrica a numerelor :x este17 minus 12√2 si y este 17plus 12√2

Answer 1

[tex]x=17-12\sqrt2\\ y=17+12\sqrt2\\ m_a=\dfrac{17-12\sqrt2+17+12\sqrt2}{2}=\dfrac{2 \cdot 17}{2}=17\\ m_g=\sqrt{(17-12\sqrt2)(17+12\sqrt2)}=\sqrt{17^2-(12\sqrt2)^2}=\sqrt{289-288}\\ m_g=\sqrt1=1[/tex]

Answer 2

Ma=17-12radical2+17+12rad/2=34/2= 17 Mg=radical din(17*17-288)=1
