Explicație pas cu pas:

x = √2/5*1/√2 + √2/5*2/3√2 = 1/5 + 2/15 = 3/15 + 2/15 = 5/15 = 1/3

y = 1/√2 : 1/5√2 - 2/3√2 : 1/5√2 = 1/√2*5√2/1 - 2/3√2*5√2/1 = 5 - 10/3

= 15/3 - 10/3 = 5/3

(x + y) : 2 = (1/3 + 5/3) : 2 = 6/3 : 2 = 2 : 2 = 1

Explicație pas cu pas:

x = √2/5 ·(³⁾1/√2 + 2/3√2)

x = √2/5 ·(3+2)/3√2

x = 5√2/15√2  

x = 1/3

y = (³⁾1/√2 - 2/3√2):(1/5√2)

y = [(3-2)/3√2] ·(5√2)

y = 5√2 /3√2

y = 5/3

ma(x,y) = (x+y)/2

ma = (1/3 + 5/3)/2 = (6/3)/2 = 2/2 = 1

ma(x,y) = 1
