Bookmark or Share- Powers of i - MathBitsNotebook (A2)Method 1: When the exponent is greater than or equal to 5, use the fact that i 4 = 1 and the rules for working with exponents to simplify higher powers of i. Break the power down to show the factors of four.
- Imaginary Numbers - Math is FunInteresting! We used an imaginary number (5i) and ended up with a real solution (−25). Imaginary numbers can help us solve some equations:
- Imaginary number - WikipediaAn imaginary number is the product of a real number and the imaginary unit i, [note 1] which is defined by its property i2 = −1. [1][2] The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25. The number zero is considered to be both real and imaginary. [3]

- Imaginary Numbers, How to simplify imaginary numbers, formula, practice ...Imaginary numbers are based on the mathematical number i i. i is defined to be −1−−−√ i is defined to be − 1. From this 1 fact, we can derive a general formula for powers of i i by looking at some examples.
