Question

Which equation demonstrates the multiplicative identity property?

(-3+5i)+0=-3+5i

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

(-3+5i)(-3+5i)=-16-30i

(-3+5i)(3-5i)= 16+30i

Answer 1

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

Explanation:

The multiplicative identity is given by :

`a* 1=a`

Where

a can be any number

Out of 4 options, in option (2), (-3+5i) is multiplied by 1 and after multiplying we get (-3+5i).

Hence, the correct option is (b).
