Question
Perform the indicated operations and write in standard form.
Sq root of -25(3- sq root of -81)
Sorry, I don't know how to do the square root symbol.
I keep getting 15i-45i^2, which would be 45+15i in standard form, right? But my teacher says it's wrong, so what am I doing wrong? Thanks a lot, guys.
