Question

simplify the imaginary number, square root of -17.

Answer 1

\[\sqrt{-17}\] = 4

Answer 2

That's just an approximation, though.

Answer 3

\[\Large\rm \sqrt{-17}=\sqrt{-1\cdot17}=\sqrt{-1}\cdot\sqrt{17}\]We denote the imaginary unit square root of -1 as i,
\[\Large\rm \sqrt{-1}=\mathcal i\]Which gives us,\[\Large\rm \mathcal i \sqrt{17}\]

Answer 4

But yah if you were looking for an approximation.. I guess it's uhhh.. 4-ish 0_o
