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

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

Step-by-step explanation:

The multiplicative identity is given by :

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).  

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
