Question

media aritmetica a numerelor 2-√3si2+√3 este egala cu

Answer 1

m a =(2-√3+2+√3):2
m a = (2+2):2
m a = 4:2
m a =2

Se reduc termenii opusi , -√3 si +√3

Answer 2

$m_{a} = \frac{a+b}{2} -formula \\ \\ m_{a} = \frac{2- \sqrt{3} +2+ \sqrt{3} }{2} \\ \\ m_{a} = \frac{2+2}{2} \\ \\ m_{a} = \frac{4}{2} \\ \\ m_{a} =2$
