Step-by-step explanation:
Complex numbers are the numbers represented by the expression = a + bi
Here a = real part of the number
bi = imaginary part
a and b are the real numbers.

[Since,
]

Therefore, its a non real complex number.
2 -
= 
= 
=
This number is a Non real complex number.

= 18i
It's a non real complex number.
3 + 2i
It's a non real complex number.
-289
It's a purely real number.

= 4 + 32
= 36
It's a purely real number.
B, because you can't get the square root of a negative number
Answer:
hmm
Step-by-step explanation:
lettt meee thinkkkkkk
Let A = 0.0009, it is equivalent to A = 9^-4 = (9^-2)^2
so sqrt A =sqrt (9^-2)^2 = (9^-2)
<span>he real square roots of 0.0009 is 0.09</span>
