xy=27 and logxY + logyX =5/2
find x and y

anyone know the answer?

What exactly do you mean by logxY and logyX? What are capital X and Y?

doraemonkiller · 01-02-2006, 01:41 PM

u took additional math too?
gosh im bad in logarithm...

Sorry I don't understand your notation. Do you mean by logxY=c that x to the power c equals Y (x^c=Y)?

i duno how to explain

doraemonkiller · 01-02-2006, 01:59 PM

xy=27 and LOGxY + LOGyX =5/2

sorry for double post

urm im stuck here:

logxY + logyX =5/2

log Y / log X + log X / log Y = 5/2

ooers...
hrm, i got to this:

log yY / log yX + log xX / log xY = 5/2

1 / log yX + logyX = 5/2

now idk wut to do lorl
