Answer:
3-i
Step-by-step explanation:
1-5i + 2 +4i
We add the real parts
1+2 =3
We add the imaginary parts
-5i + 4i = -1i
The complex number is 
3-i
 
        
             
        
        
        
Answer:

The equation which is results from taking the square root of both sides of the provided equation is,

<h3>What is the square root?</h3>
A square root of a number is the value which is when multiplicand by itself gives the same value as the number posses.
Let a number is <em>a. </em>Then this number in the form of square root can be written as,
 
 
The given algebraic equation in the problem is,

Take the square root, in both sides,

Cancel out the square root with the square of the number as,

Hence, the equation which is results from taking the square root of both sides of the provided equation is,
