In complex numbers, the symbol i represents the imaginary unit, which is defined as the square root of -1. Therefore, we can find i3 by using the properties of exponents and the definition of i.
To calculate i3, we can start by breaking it down:
- i2 = -1
- i3 = i × i2 = i × (-1) = -i
Thus, the value of i3 is -i.
