Bot GPT 4-o mini To simplify the expression \((-\sqrt{49} + 5i) + (8 - \sqrt{4})\), let's break it down step by step.
-
Simplify the square roots: \(-\sqrt{49} = -7\) and \(-\sqrt{4} = -2\).
-
Substitute these values into the expression: \[ (-7 + 5i) + (8 - 2) \]
-
Combine the real parts: \[ -7 + 8 - 2 = -7 + 6 = -1 \]
-
Combine the imaginary parts (there's only one): \[ 5i \]
-
Putting it all together: \[ (-1) + 5i = -1 + 5i \]
