Answer

The real part of the complex number $\sqrt 3 + \sqrt -4$ is $\sqrt 3$ and the imaginary part is 2.

Work Step by Step

Complex numbers are written in the form a+bi, with a being the real number and b being the imaginary number. A is $\sqrt 3$ so $\sqrt 3$ is the real part of the complex number. In order to find the imaginary part, simplify $\sqrt -4$ to $i\sqrt 4$, since $i = \sqrt -1$. $\sqrt 4$ = 2, so the imaginary part (b) of the complex number is 2.
