Suppose a(1),a(2),a(3),b(1),b(2),b(3),c(...

Suppose `a_(1),a_(2),a_(3),b_(1),b_(2),b_(3),c_(1),c_(2),c_(3)epsilon R`. Let
`Delta=|(b_(2)c_(3)-b_(3)c_(2),c_(2)a_(3)-c_(3)a_(2),a_(2)b_(3)-a_(3)_(2)),(b_(3)c_(1)-b_(1)c_(3),c_(3)a_(1)-c_(1)a_(3),a_(3)b_(1)-a_(1)b_(3)),(b_(1)c_(2)-b_(2)c_(1),c_(1)a_(2)-c_(2)a_(1),a_(1)b_(2)-a_(2)b_(1))|`
If `Delta=47.61`
then `1|(a_(1),b_(1),c_(1)),(a_(2),b_(2),c_(2)),(a_(3),b_(2),c_(3))|=1`______________
