Suppose
x^(n) = a^(m) - b^(m)
here n=/=m & a=/=b. n & m both should be greater then 2.
I want a solution to this equation where "a" & "b" are coprime ( i.e having no common factor between them) .
Can u help me out?

R travels due north on the y axis. S travels in a direction directly towards R at all times. S eventually approaches the y axis going
(almost) due north. At that time, how far ahead is R?
I graphed this and came up with .41d.
Can anyone tell me what function or series represents S's course, and how they solved this?
Thanks for any help you can give me.

A friend told me that if you plant an apple seed it can grow into any type (or new type) of apple tree. The only way to grow a specific type of apple is to take a clipping from that specific tree and grow it from that rather than a seed. Is this true?

Three of us went to a hotel and we had $10 each. Our bill was $30 and we gave $10 each. a discount of $5 was given. Dividing $5 is tough between 3, so we gave $2 tips and took $1 each. So now we spent $9 each. 9*3=$27 plus $2 tips = $29. What happened to the remaining dollar.

Could this really be possible?

I thought dogs and cats had completely incompatible genes/chromosome counts which meant this would be impossible. I mean they're not even closely related species are they?

Is it true that if you get struck by lightning, that you're more likely to be struck again? I hear lots of stories about people that have been struck more than once.
