liczba odwrotna dla 4-pierwiastek z 2

liczba: 4 - √2 liczba odwrotna: 1 / (4 - √2) = (4 + √2) / [(4 - √2)(4 + √2)] =( 4 + √2) /(16 - 2) = (4 + √2) / 14

x = 4 - √2 liczba odwrotna y to taka, że: 1 = x*y y = 1/x = 1/(4 - √2) = (4 + √2)/(4² - (√2)²) = (4 + √2)/(16 - 2) = (4 + √2)/14 y = (4 + √2)/14 jak masz pytania to pisz na pw
