Evaluate the expression (SQRT of 3 - SQRT of -4) x (SQRT of 6 - SQRT of -8) and express the result in a + bi form.
I have the answer:
- SQRT of 2 - 4 SQRT of 6i
but have no clue how to get to it. We're not allowed to use calculators for this, so I'm trying to find a way not to. This is my first post, so I'm really sorry if I'm doing something wrong. Also, does anyone know how to type the square root sign? I hope I displayed my problems correctly - any questions, just ask! Thanks.
