Rephrasing and recognizing: First, let's rephrase the  ＂Express the radical using the imaginary unit, i, and simplify the expression ±sqrt(-20).＂Separating the square root: Recognize that the square root of a negative number involves the imaginary unit i, where i^2 = -1. We can express ±sqrt(-20) as ±sqrt(-1 * 20).Replacing sqrt(-1) with i: Separate the square root of the product into the product of square roots, knowing that sqrt(a * b) = sqrt(a) * sqrt(b). This gives us ±sqrt(-1) * sqrt(20).Simplifying sqrt(20): Replace sqrt(-1) with i, since they are equivalent. This transforms the expression into ±i * sqrt(20).Taking the square root of 4: Simplify sqrt(20) by factoring it into sqrt(4 * 5), since 4 is a perfect square and its square root can be easily calculated.Combining constants outside the radical: Take the square root of 4, which is 2, and bring it outside the radical. This leaves us with ±i * 2 * sqrt(5).Combine the constants outside the radical to simplify the expression. This results in ±2i * sqrt(5).
