'i' is often used to represent the imaginary part of a complex number, and is equal to the square root of -1.

"i" is the square root of -1. Since there is no real number whose square is negative, i is an imaginary number.

Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.

e is not an imaginary number. e is Euler's constant.Uh...imaginary numbers can equal almost any number in math; it depends upon the application.Imaginary numbers can represent 1 or -1; it depends upon the applicaiton.1e is not prime; it is Euler's constantNothing in the question I posted has an exponent of zero.

Different application.The number e to the power of zero is not an issue in this problem (it equals 1)An exponent can be a positive or negative number.

An imaginary number is a number that has the square root of -1 as one of its factors.

The only thing I can think of that you might mean is an imaginary or complex number. Since there is no solution to √(-1) mathematicians labeled it as i which is the imaginary number, and any number that includes purely i is also imaginary. Complex numbers are a mix of both real and imaginary numbers. for example 3 is real, 5i is imaginary and 3+5i is complex. Hopefully this answers what you meant.

The imaginary unit number is the square root of -1 and is denoted by i

An imaginary number is a multiple of the square root of -1. A complex number is a number comprising a real part and an imaginary part.

"i" stands for imaginary. It represents the square root of -1.

I got -1.

Mathematicians decided that, since the square root of a negative number does not exist, they would use the first letter of "imaginary" to represent this "value".

A non complex number is a number that does not have any imaginary component. An imaginary component is a non zero factor of the square root of -1, in other words, the imaginary number i.

You can describe it as a number defined such that i squared = -1.You can also define the complex plane first, and then describe an imaginary number as a complex number in which the real part is zero.

Imaginary number is a number that consist of only Imaginary part. Such as i, 40i, 1/2i, etc. While the difference between the imaginary numbers and the complex numbers are that complex number also contains Real numbers, and can be written as a + bi. For example, 30+i, 1/2+1/2i, etc.

The imaginary number (i) is defined as the square root of -1. If you multiply i by i you get -1

The square root of -1 is not a real number like -2.5, 0, or 5. Instead, it is and imaginary number, i, and i = the square root of -1. The answer is imaginary because you can never take a real number, square it, and get a negative number. However, i^2 = -1.

This is an imaginary number. √-6 is an imaginary number. This imaginary number is i. This i is a number such that i = √-1 or i2 = -1. So, √-6 = √6 * √-1. From the above equation, we know that √-1 = i. Therefore, √-6 = i√6 **The "i" will always be outside of the square root sign.

Imaginary and complex numbers are an extension of the Real Number system. They are not called unreal. An imaginary number is a non-existent number, like the square root of a negative number. For example, the square root of -4 is 2i (i stands for imaginary). There are also complex numbers, which are defined as the sum of a real number and an imaginary number (e.g. 4 + 3i). An imaginary number does not exist, but can nevertheless be useful in certain applications. An imaginary number is any number that is the product of a real number and the square root of negative one (-1). The square root of -1 is the "unit" of the set of imaginary numbers, and is referred to as "i". As you know, negative numbers cannot have square roots, and so the square root of any negative number is "imaginary". There are also "complex numbers", which are the sum of a real number and an imaginary number. For example 3 + 2i.

No. For example the number 1+i. Pure imaginary complex numbers are of the form 0 + a*i, where a is a non-zero real number.

number * 1

the square root of -1 is an imaginary number

i x i = -1

The number one always means the same thing, at any size font. However, you may be thinking of the letter i. That is used to mean an imaginary number defined as the square root of minus one.

It depends on the level that you are at. For more advanced mathematics, the square root of -1 is a number, denoted by i. It is a basic element of complex numbers and is called the imaginary root of -1.

No. All Complex Numbers are of the form a + bi where a and b are Real Numbers and i is the square root of -1. So only ones where a = 0 are pure Imaginary Numbers.
