Przekształć ułamek do prostszej postaci :
a) 4/ pierwiastek z 3 + 1 =
b) 2 pierwiastek z 3 - 1/ 2 - pierwiastek z 3 =
a)
4/(V3 +1) = 4/(V3 +1) *(V3 -1)/(V3 -1) = 4(V3 -1)/(3-1) =4(V3 -1)/2 = 2(V3 -1)
b)
(2V3 -1)/(2-V3) =(2V3 -1)/(2-V3) *(2+V3)/(2+V3) =(2V3 -1)(2+V3)/(4-3)=
= (4V3 +2 *3 -2 -V3) = 3V3+4
