Answer:
The square root of -1 is defined as "i"
Step-by-step explanation:
The square root of 9 is 3, as 3 x 3 = 9.
The square root of 4 is 2, as 2 x 2 = 4.
The square root of 1 is 1, as 1 x 1 = 1.
The square root of 0 is 0, as 0 x 0 =0.
But... what's the square root of -1? You can't multiply any two numbers to get -1, as when you multiply two numbers with the same sign, you obtain a positive product.
Because of this, it is defined that "i" is equal to the square root of -1. "i" stands for "imaginary," as there is no real number that is the square root of -1.
