oh well...here we go...

| 3 4 3 |
| 2 2 2 | now we have the 3x3 determinent...
| 5 6 6 |


3 |2 2| = 3(12 - 12) = (3) ( 0 ) = 0
|6 6|

4 |2 2| = -4(12 - 10) = (-4) (2) = -8
|5 6|

3 |2 2| = 3(12 - 10) = (3) (2) = 6
|5 6|

0 - 8 + 6 = -2

so the answer is -2.... the vectors are linearly independent...
Yippi!....I tought someone would've studied a bit of linear algebra...oh well!....
