Respuesta :
Option B is correct. (-3 + 5 i) (1) = (-3 + 5 i) satisfy the multiplicative identity law
The multiplicative identity property states that a function value or function remains the same when 1 is multiplied by such value. For instance;
- A × 1 = 1 × A = A (multiplicative identity property)
From the given option, the expression that satisfies the theorem above is (-3 + 5 i) (1) = (-3 + 5 i)
We can see that when -3 + 5i is multiplied by 1, the result remains the same.
The rest of the option does not satisfy the condition since none of them is multiplied by unity.
