I 3 Equals

Now just do the multiplication.

I 3 equals. But then people researched them more and discovered they were actually useful and important because they filled a gap in mathematics. And that is also how the name real numbers came about real is not. An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i which is defined by its property i 2 1. You don t have to remember various special.

The set of imaginary numbers is sometimes denoted using the. Imaginary numbers were once thought to be impossible and so they were called imaginary to make fun of them. For example simplify i as i. I 3 i 2 i 1 i i.

Learn how to simplify any power of the imaginary unit i. Ninety six is a multiple of four so i 96 is just 1 which you can ignore in other words you can divide the exponent by 4 using long division discard the answer and use only the remainder. But the imaginary name has stuck. Since you said that you already know what i 2 is then you re almost there.

Learn about the imaginary unit i about the imaginary numbers and about square roots of negative numbers.
