Which equation demonstrates the multiplicative identity property

Equation b) (-3 + 5i) (1) = -3 + 5i  demonstrates the multiplicative identity property

There are several properties in integer multiplication operations

Multiplication between integers will produce integers too

a x b = b x a

ax (bxc) = (axb) xc

ax1 = 1 x a = a

* addition

ax (b + c) = axb + axc

* substraction

ax (b-c) = axb - axc

The Multiplicative Identity is 1

The multiplicative identity property states that any number multiplied by 1 will produce an original number.

We complete the answer choices available from the problem above:

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

O is an identity in the sum operation, the statement is false

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

1 is a Multiplicative Identity of multiplication, so the statement is true

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

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

choice c and is a multiplication factor, so the statement is false

the substitution method
