Best ResponseYou've already chosen the best response.0combine like terms under and the multiply it all by the conjugate of your denominator

Best ResponseYou've already chosen the best response.0to combine like terms, just consider the "i" like any other variable

Best ResponseYou've already chosen the best response.0are you saying 54i is the answer?

Best ResponseYou've already chosen the best response.0the conjugate thing might be overkill, since its hard to determine what is meant by "simplify"

Best ResponseYou've already chosen the best response.0..... no, the denominator of a fraction is never "the answer" to an entire problem

Best ResponseYou've already chosen the best response.0forgot the original problem :) \[\frac{\sqrt{64}}{54i}\]

Best ResponseYou've already chosen the best response.0the top simplifies to 8i since:\[\sqrt{64}=\sqrt{64*1}=\sqrt{64}\sqrt{1}=8i\]

Best ResponseYou've already chosen the best response.0then its a conjugate thing im sure :) \[\frac{8i}{54i}*\frac{5+4i}{5+4i}=\frac{40i+32i^2}{2516i^2}=\frac{40i32}{25+16}\]

Best ResponseYou've already chosen the best response.0looks like it might shape up to the last one

Best ResponseYou've already chosen the best response.0well, from what ive written so far, im prettu sure 32 is 32; +40i is +40i; amd 25+16 is 41 ... so putting this altogether I tend to be leaning towards the last one since it fits all the parts :)

Best ResponseYou've already chosen the best response.0good luck, conjugates and is tend to not come up alot, so you have a tendency to forget about them
