Question

1. use the commutative property of addition to reorder the expression below. 7 - 4i 7i + 4 7 + 4i -4i + 7 4i - 7

Explanation:

Step1: Recall commutative property

The commutative property of addition states that for any two numbers \(a\) and \(b\), \(a + b=b + a\). The expression \(7-4i\) can be written as \(7+( - 4i)\).

Step2: Apply the property

By the commutative property of addition, \(7+( - 4i)=-4i + 7\).

Answer:

-4i + 7 (corresponding to the option \(-4i + 7\))
