`|{:(a+b,a+2b, a+3b), (a+2b,a+3b,a+4b), (a+4b,a+5b,a+6b):}|` का मान है

Select and write the correct answer from the given alternatives in each of the following: |(a+b,a+2b,a+3b),(a+2b,a+3b,a+4b),(a+4b,a+5b,a+6b)| =

|{:(a+b,2a+b,3a+b),(2a+b,3a+b,4a+b),(4a+b,5a+b,6a+b):}|=0

The value of |{:(a,a+2b,a+4b),(a+2b,a+4b,a+6b),(a+4b,a+6b,a+8b):}| is

Using properties of determinants, prove that: |{:(a, a +b, a+b+c),(2a, 3a + 2b, 4a + 3b + 2c),(3a, 6a+3b, 10a + 6b + 3c):}| = a^(3)

Evaluate : |{:(a,a+b,a+b+c),(2a,3a+2b,4a+3b+2c),(3a,6a+3b,10a+6b+3c):}|

Prove that |{:(a,a+b,a=b+c),(2a,3a+2b,4a+3b+2c),(3a,6a+3b,10a+6b+3c):}|=a^3

If a : b = 3 :sqrt5 , then the value of (2a + b) : (3a - 2b) is: यदि a : b = 3 :sqrt5 , तो (2a + b): (3a -2b) का मान है:
