Which equation demonstrates the multiplicative identity property?
Answer
A
open paren negative 3 plus 5 i close paren times open paren 3 minus 5 i close paren is equal to 16 plus 30 i
B
open paren negative 3 plus 5 i close paren plus 0 is equal to negative 3 plus 5 i
C
open paren negative 3 plus 5 i close paren times 1 is equal to negative 3 plus 5 i
D
open paren negative 3 plus 5 i close paren times open paren negative 3 plus 5 i close paren is equal to negative 16 minus 30 i
Explanation
The multiplicative identity property says that multiplying any number by 1 leaves it unchanged. Choice B shows (−3 + 5i) × 1 = −3 + 5i, so it demonstrates this property.
