1. If you add the like terms, you get this equivalent expression:
2. But if you factor out 3, you get the following equivalent expression:
Therefore, the expression shown in Choice A and Choise B are equivalents to the expression
Answer:
Step-by-step explanation:
Given the expression:
To find:
The expression of above complex number in standard form .
Solution:
First of all, learn the concept of (pronounced as <em>iota</em>) which is used to represent the complex numbers. Especially the imaginary part of the complex number is represented by
.
Value of .
Now, let us consider the given expression:
So, the given expression in standard form is .
Let us compare with standard form so we get
.
The standard form of
is:
