Best ResponseYou've already chosen the best response.2If you have something in the form \(\sqrt{a}\) for some \(a > 0\), then we can break it up using exponent / radical properties: \(\sqrt{a} = \sqrt{1 \times a} = \sqrt{1} \sqrt{a} = i \sqrt{a} \)

Best ResponseYou've already chosen the best response.2\(i \sqrt{16}\) Yes, although we can go a step further since \(\sqrt{16}\) is the square root of a perfect square. = \(4i\)
