Square Root Property With Imaginary Numbers. Imaginary numbers are used to help us work with numbers that involve taking the square root of a negative number. That s the geometric property i mentioned.
Imaginary numbers are used to help us work with numbers that involve taking the square root of a negative number. In this tutorial you ll be introduced to imaginary numbers and learn that they re a type of complex number. This video looks at simplifying square roots with negative numbers using the imaginary unit i.
It includes 6 examples.
And so there is nothing to prevent us from making use of those numbers and employing them in calculation. The two square roots of 3i lie on the line at itex pi 4 itex radians or 45 degrees to the positive real axis at distance itex. We call it a complex or imaginary number. We know as that number which when squared produces 3.
