Question

Find the real-number root.
sqrt -1.69

Answer 1

\[\sqrt{-1.69}\]

Answer 2

Because the radicand (the quantity under the radical operator) is negative, this expression has NO real roots. However, you could, out of curiosity, factor Sqrt(-1.69) into Sqrt(-1)*Sqrt(1.69). Sqrt(-1) is defined as i (imaginary quantity). Thus, Sqrt(-1.69) = -Sqrt(1.69) = ??

Answer 3

oh okay!
