Is that all that I have to do? I'm not really sure how to do these sorts of problems

You need to multiply out the brackets and simplify if possible

Just like normal except you have i's to deal with...

6(3i)? Wouldn't the bottom cancel itself out?
 one year ago

It is a kind of trick to get rid of the i on the bottom.....

Similar to how you get rid of a rdical, same sort of idea...

which you could divide 9 by 9 to get one, so i?

6(3i) is 186i Where do you get 9i from?

Oh wow opps. haha I added.

estudierBest ResponseYou've already chosen the best response.1
Ok, now what do you get for the bottom?

estudierBest ResponseYou've already chosen the best response.1
You have (3+i)(3i) Tell me how it comes to 9
 one year ago

gfields444Best ResponseYou've already chosen the best response.0
You multiply and the +i and i cancel out? i'm really sorry, this is new to me haha

estudierBest ResponseYou've already chosen the best response.1
(3+i)(3i) is 3*3 + 3*i 3*i  i^2 (using FOIL?)
 one year ago

estudierBest ResponseYou've already chosen the best response.1
So the 3i's cancel out and leave 9i^2 So what is i^2 ?
 one year ago

estudierBest ResponseYou've already chosen the best response.1
Right, so what is the bottom ( hintit is not 9)
 one year ago

estudierBest ResponseYou've already chosen the best response.1
Ok so finally you have 186i/10 which you can divide by 2 to get 93i/5 as a final answer.
 one year ago

estudierBest ResponseYou've already chosen the best response.1
So, procedure for these is *by conjugate top and bottom then simplify
