If the value in the radicand is negative, the root is said to be an imaginary number. The imaginary number i is defined as the square root of negative 1. \[\sqrt{-1}=i\] So, using properties of radicals, \[i^2=(\sqrt{-1})^2=−1\] We can write the square root of any negative number as a multiple of i.
