Question

Which equation demonstrates the multiplicative identity property?
(negative 3 + 5 i) + 0 = negative 3 + 5 i
(negative 3 + 5 i ) (1) = negative 3 + 5 i
(negative 3 + 5 i) (negative 3 + 5 i) = negative 16 minus 30 i
(negative 3 + 5 i) (3 minus 5 i) = 16 + 30 i

Answer 1

(-3 + 5i)(1) = -3 + 5i

This shows the multiplicative identity property because multiplying any number by 1 leaves it unchanged.
