Question

If each element of a determinant of 3rd order A is multiplied by 3, then the value of newly formed determinant is........

​

Answer 1

Answer:

27|A|

Step-by-step explanation:

the answer is 27 times of original determinant because we take out common from a single row or column of a determinant which is not like the case of matrix in which we take common from all the elements in a matrix

so since the determinant is of order 3 therefore it will have 3 rows(/columns) and that is why we take 3 common 3 times which is equal to 3x3x3=27
