Question
Simplify. Write each result in a + bi form.$$(8-\sqrt{-5})(-2-\sqrt{-7})$$
Step 1
First, we can distribute the terms in the expression: $(8-\sqrt{-5})(-2-\sqrt{-7}) = 8(-2) + 8(-\sqrt{-7}) - \sqrt{-5}(-2) - \sqrt{-5}(\sqrt{-7})$ Now, we can simplify each term: $8(-2) = -16$ $8(-\sqrt{-7}) = -8\sqrt{-7}$ Show more…
