How do you perform imaginary numbers computations?
Imaginary numbers come in handy to do many computations, especially something called simplification. Here are some “simple” examples of how to use imaginary numbers:
To simplify the square root (or sqrt) of -25:
To simplify 2i + 4i:
To simplify 21i - 5i:
To multiply and simplify (2i)(4i):
(2i)(4i) = (2 × 4)(ii) = (8)(i2) = (8)(-1) = -8
