Question

Find the product and enter the real and imaginary parts below. Note that you do not need to type in the since it is already given to you. Simplify your square roots as much as possible.
sqrt-27((sqrt-5)-(sqrt-11))

Answer 1

use i notation: i= sqrt-1, i^2=-1

i*sqrt(9*3) [i sqrt5-i sqrt11)

3sqrt3(i^2 sqrt5 -i^2 sqrt 11)
-3 sqrt (15) +3 sqrt 33

check that.
