Haha lol, an egg pretty much...

1/3 + 1/4 + 1/5 = 1/Rt

47/60 = 1/Rt

Rt = 60/47 = ???
That is what i did

Why do you do the inverse at the end ?

Ryan
Because we have 1/total resistance when we add up the other fractions so we have to find the inverse by raising it to the power of -1 , to get total resistance/1 which is the value we want...It's the same as finding the reciprocal

Because he got it wrong (no offence )

1/3 + 1/4 + 1/5 = 0.783... (he put 1/0.783, which is wrong)
And then you find the inverse of 0.738, giving you 1/0.783 = 1.28

That's what I meant...I think

You don't put it to the power of -1, you just divide 1 by the denominator from the first stage

Which is the same as to the power -1..

Which is the same as to the power -1..
But you don't both divide 1 by your answer and put it to the power of -1...

e.g. 1/3.5 = 0.285714

(1/3.5)^-1 = 3.5

Q.E.D

I'm confused

I didn't say both

I was referring to BP's question, I guess you didn't read it? That's what confused us :P

Isn't divided by one to the power of minus 1 the exact same of doing nothing to it?

No... it's the reciprocal

I feel the same as you.. my head does not have the capacity for anymore revision
I know... I've lost all my drive to get those results... I just want this to be over with!
20. So then who's the smartest here?
