To find: The value of the given determinant.
Answer to Problem 13CT
The value of the determinant is
Explanation of Solution
Given information:
The given determinant is
Calculation:
If each element in one row or one column of a determinant is multiplied by a real number
Factor out
Factor out
From the above calculation we note that in the above determinant the corresponding element in the first row and the second row are the same.
If two row or two columns of a determinant have corresponding element that are equal, then the determinant is equal to zero.
Therefore, the value of the determinant is
