If b ≠ 0, then a + bi is an imaginary number. If a = 0 and b ≠ 0, then a + bi is a pure imaginary number. The diagram shows how different types of complex numbers are related. Complex Numbers (a + bi) Real Numbers (a + 0i) Imaginary Numbers (a + bi, b ≠ 0) Pure Imaginary Numbers (0 + bi, b ≠ 0) −1 2 + 3i 9 − 5i −4i 6i 5 3 π 2 The ...
Learn about the imaginary unit i, the square roots of negative numbers, and how to simplify pure imaginary numbers. See examples, practice problems, and video transcript.
- what would -i^-i be, would it just be 2^2it would be i^3(i^3) = -1^(-1) = 1/-1 = -1

- hard to believe there are people out there that imagine numbersTechnically, numbers and mathematics in general are all imaginary. Mathematics is not a physical object that literally exists in the seeable univer...
- Can you have different answers to simplifying depending on what numbers you take from the original, ...They were asking for the square root. The square root of 4 is 2 so you would have 2i sqrt(6) ... The cubed root of 8 is 2 not the square root.
- this make no sensesimple actually, the key here is to understand what "i" means; normally the square root of any negative number is impossible to find, because multi...
- Does it matter if the i is in front or behind of the solution.As long as it is clear what the i is affecting, you can do both. EG (2 + 3i) + (4 + 5i) = (2 + 4) + i(3 + 5) or (2 + 4) + (3 + 5)i However, there a...
- How would one use an imaginary number in real life? If it is imaginary, would it have any use cases?...Imaginary numbers are used a lot in electrical engineering. They can also used to prove a lot of formulas that are useful in real life. And they ar...
- Where is I on the number line?Great question! You can't find i on the number line because it only represents real numbers. So, instead we use the complex *plane* to represent th...
- If imaginary numbers aren't real, how is it possible to use them in real life? You can't count thing...None of the numbers you use in life are real. Can you show me a 3? Not a drawing or a representation of a 3, but the actual number 3? Of course not...
