If a number is pure imaginary then it has no real component. If it is a real number, then there is no imaginary component. If it has both real and imaginary components, then it is a complex number.
an imaginary number is imaginary so no (i guess) this answer kind of sucks
-125 is NOT an imaginary number.
A pure imaginary number is a complex number that has 0 for its real part, such as 0+7i.
Assuming that "imaginary" refers to i, then the answer is yes.Assuming that "imaginary" refers to i, then the answer is yes.Assuming that "imaginary" refers to i, then the answer is yes.Assuming that "imaginary" refers to i, then the answer is yes.
A real number is any number between minus and plus infinity, or it is not an imaginary number.
Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.

-125 is NOT an imaginary number.
That quotient would be an imaginary number. The actual number depends on exactly what imaginary number you divide the 7 by.
It is a pure imaginary number.Since (a+bi)-(a-bi) = 2bi, it is a pure imaginary number (it has no real component).
No, but √-23 is. An imaginary number is the square root of a negative number.
No. A complex number is a number that has both a real part and an imaginary part. Technically, a pure imaginary number ... which has no real part ... is not a complex number.
No. It is an imaginary (or complex) number.
No, it is an imaginary number which is a complex number.
The imaginary unit number is the square root of -1 and is denoted by i
