An imaginary number is a number that cannot exist. An example of an imaginary number would be: the square root of negative nine, or any negative number.
When I try to think of any two of the same numbers that would multiply together to be negative nine, all I can think of is 3 or -3. when I square both of those numbers, I get the number 9, not -9. When I multiply two negatives together, I get a positive number, therefore there is no possible way to get the square root of -9, or any negative number.
What else can I help you with?
Can a no real number be a pure imaginary number?
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.
Can you divide an imaginary number by a real number?
an imaginary number is imaginary so no (i guess) this answer kind of sucks
How do you simplify the imaginary number -125?
-125 is NOT an imaginary number.
Whats an imaginary number?
An imaginary number is a number that has the square root of -1 as one of its factors.
What is the definition of a pure imaginary number?
A pure imaginary number is a complex number that has 0 for its real part, such as 0+7i.
Is 13i pure imaginary?
Yes, (13i) is a pure imaginary number. A pure imaginary number is one that can be expressed in the form (bi), where (b) is a real number and (i) is the imaginary unit. Since (13i) has no real part and consists solely of the imaginary part (13), it qualifies as pure imaginary.
Which number belongs to the set of imaginary numbers 2?
2 does belong to the set of imaginary numbers. Any real number is also imaginary. Imaginary numbers are the set of all numbers that can be expressed as a +b*i where "i" is the square root of negative one and "a" and "b" are both real numbers.
What is -7i?
-7i is a purely imaginary number in the complex number system, where "i" represents the imaginary unit, defined as the square root of -1. It can be expressed in the form a + bi, where a is the real part (0 in this case) and b is the imaginary part (-7). This number lies on the imaginary axis of the complex plane, indicating it has no real component.
Is the square root of 28 imaginary?
No but the square root of 28 is an irrational number that can't be expressed as a fraction
Is the square root of 28 integral or imaginary?
The square root of 28 is an irrational number that can't be expressed as a fraction
How can you tell which part of a complex number is the real part and which is the imaginary part?
The imaginary part is expressed as a product of i(square root of negative one), typically following a plus sign, so that the complex number has the form a + bi, with "a" the real part and "bi" the imaginary part.
Can you take the log of an imaginary number?
Yes, you can take the logarithm of an imaginary number, but it's more complex than with real numbers. The logarithm of a complex number, including imaginary numbers, is defined using the polar form of the number. For an imaginary number like ( bi ) (where ( b ) is real), the logarithm can be expressed as ( \ln|b| + i\arg(b) ), where ( \arg(b) ) is the argument (angle) of the complex number in the complex plane. Thus, the result will also be a complex number.
How is a complex number defined?
A complex number is a two-dimensional continuous quantity that is the sum of a real number and an imaginary number expressed in the form a+bi and plotted on a complex coordinate plane with the real line on the horizontal x-axis and the imaginary line on the vertical y-axis.
Is the square root of -3 irrational?
The square root of -3 is an imaginary number and the square root of 3 is an irrational number that can't be expressed as a fraction
Can a number be imaginary but not pure imaginary?
Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.
What is te square root of -120 to the nearest integers?
The square root of a negative number cannot be expressed with integers. The square root of a negative number is always imaginary.
What is subset of imaginary numbers?
A subset of imaginary numbers consists of numbers that can be expressed in the form (bi), where (b) is a real number and (i) is the imaginary unit, defined as (i = \sqrt{-1}). This subset includes numbers like (2i), (-3.5i), and (0.1i). Imaginary numbers can be thought of as a special case of complex numbers, which have both a real part and an imaginary part.
