A complex number is a number of the form a+bi, 

if b=0, that is if the number is a, then it is a Real number

if a=0, that is if the number is bi, then it is called an imaginary number.



All imaginary numbers are complex numbers.

Also, all real numbers (non-imaginary) are complex numbers.


Thus, all the numbers given are complex.

3i   :   imaginary

-5i :    imaginary

6-i:    complex

square root of 21: real, non-imaginary, complex

Negative square root of 16=-4:  real, non-imaginary, complex

<span>Square root of -14 = (square root of 14)i:   imaginary</span>

Answer:

The value of x is \frac{-2}{5}.

Step-by-step explanation:

Given expression is:

\frac{2}{3}(x-2)=4x

We have to solve this for x.

First we will multiply both sides of the equation by 3

3*\frac{2}{3}(x-2)=4x*3

2(x-2) = 12x

2x-4=12x

Now we will be subtracting 2x from both sides of the equation

2x-2x-4=12x-2x

-4=10x

10x=-4

Dividing both sides by 10

\frac{10x}{10}=\frac{-4}{10}\\\\x=\frac{-2}{5}

Hence,

The value of x is \frac{-2}{5}.
