I know I have to distribute and also I can do like terms

distribute 2nd parentheses by negative one

yeah igot tha tpart already im confused as to the rest...

alright show ur work

then 54 minus the 39 and now im stuck.

I bleive its 15 addition to something

well you didn't distribute the 2nd parentheses

why is it 27{-1} = ?

sq to power of 2?

-1 x -1 imaginary number

oh well no i = sqrt{-1}
i^2 = -1
but there isn't any i^2

so its not power of two?

uh -5?

so 27i + -5i?

so -39 + -5i?

yes right

i thought you needed like terms?

yes right now we have like terms |dw:1442335143368:dw|
combine like terms

32i btw

if we have negative sign outside the parentheses we must hve to distribute first

hmm -27i-5i = ?

i guess so

but it has minus

yes it supposed to be -32
-# -# = -#

so far i se 15 - 32i? am I steearing in the righ tdirection?

yes that's right

- hashtag lol

So am I done now ? because I need help with more if you have time to spare explaining a few with me.

yes that's itdone!

ooo that came out messy maybe I can attach a file

ok done. :D

sorry my internet went bye bye lol

ok so now what?

that's it

im lost?

nvm i got it 7/3?

no that's not right

hmm?

index would be the `denominator`

ooohh ohhh sorry

get it now

alright so A would be what ?

isnt the 3 the den?

yes right

because the numer became the power

alright thanks

excellent!
