The second equation (8+6i)(7-9i) = (7-9i)(8+6i) is the correct answer.
option (B) is correct.
It is required to choose the commutative property of multiplication of given equation.
The commutative property of multiplication says that you can multiply numbers in any order and the answer will always be the same. Changing the order of factors does not change the product.
Given that:
In the given question we have to find the commutative property of multiplication of given equation.
Let's consider the first equation,
(8+6i) = (6i+8)
Here commutative property of addition is used.
So, this option is incorrect.
The given second equation is,
(8+6i)(7-9i) = (7-9i)(8+6i)
In the above equation, the commutative property of multiplication is used.
So, this option is correct.
Hence, option (B) (8+6i)(7-9i) = (7-9i)(8+6i) is the correct answer.
