Wytłumaczy mi to ktoś? Bo nie ogarniam jakim cudem ma wyjść 2...
(7√18-√8-2√200)²=2
(7√9·√2-√4·√2-2√100·√2)²=2
(7·3√2-2√2-2·10√2)²=2
(21√2-2√2-20√2)²=2
(-√2)²=2
(-√2)·(-√2)=√4=2
Można tak:
(7√18-√8-2√200)(7√18-√8-2√200)=2
882-7√144-14√3600-7√144+8+2√1600-14√3600+2√1600+4√40000 = 2
882-84-840-84+8+80-840+80+800 = 2
L = P
Pozdrawiam :)
