Explicație pas cu pas:
Hristos a inviat!
x = √2/5(1/√2 + 2/3√2)⇒amplificam cu 3 fractia 1/√2
x = √2/5[(3+2)] /3√2⇒
x = √2/5 × 5/3√2⇒
x = 1/3
y = (1/√2 - 2/3√2) ÷ 1/5√2⇒amplificam cu 3 fractia 1/√2
y = (3/3√2 - 2/3√2) × 5√2/1⇒
y = 1/3√2 × 5√2⇒
y = 5/3
Ma = (x+y)/2⇒
Ma = (1/3+5/3)÷2⇒
Ma = 6/3÷2
Ma = 2÷2
Ma =1
