It says the correct answer is --> - 48/145 + 54i/145
oh...then tell me can't u write (a+b)/c= a/c + b/c
oh...then tell me can't u write (a+b)/c= a/c + b/c
I thought it was the same thing
  • phi
standard form for a complex number is a + bi where a is the real part and b the imag part. they want you to divide through by the 145 so that you have a real part -48/145 and an imaginary part 54/145 i
Okay so I have to write it separate like that when it says standard form with a fraction?
yeah u hv to seperate in form of a+ib
  • phi
yes
Great more stuff I have to remember.. Okay thank you for explaining that
  • phi
yes, math has a lot of memorizing. but it's not like learning French ... it seems like they have a different word for everything.
True.
Perform the indicated operation and write in standard form a+bi. 5 square root -64 + 6 square root -25 .... I cant remember how to solve this one -.-
  • phi
write the \( \sqrt{-64} \) as \( \sqrt{64}\cdot \sqrt{-1} \)
\[5\sqrt{-64} + 6\sqrt{-25}\]\[=5\sqrt{64}\sqrt{-1}+6\sqrt{25}\sqrt{-1}\]This help any?
  • phi
and use the short-hand "i" for sqr(-1)
That turns into 5 square root 64i +6 square root 25i right? Or am I way off?
  • phi
yes, but sqr(64) is a nice number ditto sqr(25)
Yes, but you know sqrt(64) and sqrt(25)
Sorry. I'm out. Keep up the good work.
So now I have to make them into smaller numbers...
  • phi
yes. you should know them, but you can use a calculator if you don't
8i and 5i
  • phi
ok, and you now have 5*8*i + 6*5*i (I put in the multiply signs to make it clearer) that can be simplified.
40i+30i 70i^2 70(-1) -70
  • phi
it is 40 i's plus 30 more i's
Oops so its 70i
  • phi
yes
Okay thank you... 3 more to go
