I^2=-1
T/F
True. The square root of -1 is represented by the imaginary unit "i".
True.
To understand why the statement is true, let's break it down:
In mathematics, the imaginary unit is defined as "i," which is equal to the square root of -1. So, i = sqrt(-1).
Now, to evaluate i^2, we substitute the value of i as sqrt(-1). We have:
i^2 = (sqrt(-1))^2
= (-1)
= -1
Hence, i^2 equals -1.
True.
In mathematics, the imaginary unit is denoted by the symbol "i". It is defined as the square root of -1.
So, i^2 = -1.
