Question

What would be the answer to this equation?

Im going to write it as an answer to the question so I can use the equation form.

Answer 1

\[(i \sqrt{-363})(\sqrt{-243})\]

Answer 2

find the prime factors of 363 and 243, and look for perfect squares.
Also, factor i from each root, to get i^3 out front. i^3= -i

Answer 3

i got \[-99i \sqrt{3}\]

Answer 4

yeah, remember that you need to factor the "i" out first :) i remember half the time lol

Answer 5

from factoring 11 and 9 out of the two square roots and leaving 3 under the sign.

Answer 6

I think you should get two sqrt(3) factors

Answer 7

after the first factor i get:
\[(11i ^{2}\sqrt{3})(9i \sqrt{3})\]

Answer 8

Yep. and sqrt(3)*sqrt(3)= 3

Answer 9

ohh...duhh me! omg, thanks! :)
