The complex numbers are:
[tex]1+\sqrt{-3}\\4-3\sqrt{-16}\\\frac{3+2\sqrt{-9}}{7}\\9\sqrt{-\frac{7}{5}}[/tex]
Further explanation:
Let us define complex numbers first.
Complex numbers consist of real and imaginary parts. The imaginary part usually comes from the negative term in square root.
From the given numbers the complex numbers will be:
[tex]1+\sqrt{-3}\\4-3\sqrt{-16}\\\frac{3+2\sqrt{-9}}{7}\\9\sqrt{-\frac{7}{5}}[/tex]
As all of them involve a square root which contains negative sign so the square root cannot be solved in real numbers. A new imaginary number will be introduced to solve them thus making them complex.
