Answer:

[tex]-7 + 8i[/tex]

Step-by-step explanation:

[tex](-11 + \sqrt{-4}) + (4 + \sqrt{-36}) = (-11 + 2\sqrt{-1}) + (4 + 6\sqrt{-1})[/tex]

We know [tex]\sqrt{-1}[/tex] is a complex number and is defined by [tex]i[/tex]

∴[tex](-11 + \sqrt{-4}) + (4 + \sqrt{-36}) = (-11 + 2i) + (4 + 6i) = -7 + 8i[/tex]
