2^(n) = t^(m) - w^(m)
where, n =/= m.
like,2^(4) = 5^(2) - 3^(2)
give an example for
2^(4) = t^(3) - w^(3)
where "t" & "w" are natural.

It is impossible to write
2^(n) = t^(n) - w^(n)
for n>1 having natural solutions for "t" & "w".
Prove it with guts.

I know that in a projectile motion, x and y are independent.

I have a problem that only tells me that the river is 75 m wide. I am trying to find the MINIMUM initial speed for the rock to get across the river and the time it is in the air.

Can I use the equation: distance= Vot+(1/2)9.8t^2
for an x component (b/c I only know the distance for x) to get time?

I got 3.9 s

Most scientists agree that it would be highly unlikely to find life outside this planet that remotely resembles ours. I also personally believe that the UFO phenomena can be explained (so far) without involving the proverbial "little green men", or any alien being for that matter. Nevertheless, I wonder what could happen if we begin to discover signals from different planetary systems, spreaded through the galaxy, carrying greeting messages that clearly shows that our neighbors are anatomically almost identical to us. How this knowledge could affect our science and our beliefs?
