Answer:
b) (-3 + 5i)(1) = -3 + 5i
Step-by-step explanation:
First let's see what a multiplicative identity.
The multiplicative identity property states that any time you multiply a number by 1, the result is the original number.
Therefore, 1 is the multiplicative identity.
For instance, 3 * 1 = 3
Hence, according the property
(-3 + 5t)(1) = -3 + 5i states the multiplicative identity.
Hope you will understand the concept.
Thank you.
