Best ResponseYou've already chosen the best response.0standard 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

Best ResponseYou've already chosen the best response.0yes, math has a lot of memorizing. but it's not like learning French ... it seems like they have a different word for everything.

Best ResponseYou've already chosen the best response.1Perform 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 .

Best ResponseYou've already chosen the best response.0write the \( \sqrt{64} \) as \( \sqrt{64}\cdot \sqrt{1} \)

Best ResponseYou've already chosen the best response.0\[5\sqrt{64} + 6\sqrt{25}\]\[=5\sqrt{64}\sqrt{1}+6\sqrt{25}\sqrt{1}\]This help any?

Best ResponseYou've already chosen the best response.0and use the shorthand "i" for sqr(1)

Best ResponseYou've already chosen the best response.1That turns into 5 square root 64i +6 square root 25i right? Or am I way off?

phi

Best ResponseYou've already chosen the best response.0yes, but sqr(64) is a nice number ditto sqr(25)

anonymous

Best ResponseYou've already chosen the best response.0Yes, but you know sqrt(64) and sqrt(25)

Best ResponseYou've already chosen the best response.1So now I have to make them into smaller numbers...

phi

Best ResponseYou've already chosen the best response.0yes. you should know them, but you can use a calculator if you don't

phi

Best ResponseYou've already chosen the best response.0ok, and you now have 5*8*i + 6*5*i (I put in the multiply signs to make it clearer) that can be simplified.
