Answer» यहाँ `Delta=|{:(sqrt(13)+sqrt(3),2sqrt(5),sqrt(5)),(sqrt(15)+sqrt(26),5,sqrt(10)),(3+sqrt(65),sqrt(15),5):}|` `=|{:(sqrt(13),2sqrt(5),sqrt(5)),(sqrt(15),5,sqrt(10)),(3,sqrt(15),5):}|+|{:(sqrt(3),2sqrt(5),sqrt(5)),(sqrt(26),5,sqrt(10)),(sqrt(65),sqrt(15),5):}|` `=sqrt(5)*sqrt(5)|{:(sqrt(13),2,1),(sqrt(15),sqrt(5),sqrt(2)),(3,sqrt(3),sqrt(5)):}|+sqrt(5)*sqrt(5)|{:(sqrt(3),2,1),(sqrt(26),sqrt(5),sqrt(2)),(sqrt(65),sqrt(3),sqrt(5)):}|` `=5|{:(sqrt(13)-2sqrt(3),2,1),(0,sqrt(5),sqrt(2)),(0,sqrt(3),sqrt(5)):}|+5|{:(sqrt(3)-sqrt(13),2,1),(0,sqrt(5),sqrt(2)),(0,sqrt(3),sqrt(5)):}|` `=5(sqrt(13)-2sqrt(3)(5-sqrt(6))+5(sqrt(3)-ssqrt(13))(5-sqrt(6))` `=5(5-sqrt(6))(sqrt(13)-2sqrt(3)+sqrt(3)-sqrt(13))` `=5(5-sqrt(6))(-sqrt(3))` `=-5(5-sqrt(6))sqrt(3)` |
