Question

Media aritmetica a numerelor √2 si √18 este ?

Answer 1

Ma=(a+b) :2 = (√2+√18):2= (√2+3√2):2=4√2/2=2√2
Se simplifica 4 si 2 prin 2

Answer 2

$\it m_{a} = \frac{ \sqrt{2} + \sqrt{18} }{2} = = > m_{a} = \frac{ \sqrt{2} + 3 \sqrt{2} }{2} = = > m_{a} = \frac{4 \sqrt{2} }{2} = = > \boxed{m_{a} = 2 \sqrt{2} }$
