 Question 188320This question is from textbook : 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|This question is from textbook Answer by jim_thompson5910(28598)   (Show Source): You can put this solution on YOUR website!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
