SOLUTION: use properties of determinants to find the value of each determinant if it is know that |x y z| |u v w| |1 2 3| =4 |x y z| |u v w| |2 4 6|

Remember, you can multiply a scalar value "k" by any row of a determinant like this:

Note: you can pick any row. In this example, I'm using the first row.




Start with the given equation.


Since the bottom row of the resulting determinant is 2, 4, and 6 this means that this row is 2 times the bottom row of the given determinant.



Multiply both sides by 2


Multiply the scalar 2 by the entire bottom row of the determinant


Multiply



So the answer is
