prove without using Fermats last theorem that it is imposible to write
(5a)^(n) + (5a + 2)^(n) = (v)^(n)
for natural solutions of "a" & "v" having n>1.

ok, i know this isn't possible. But let's say, hypothetically, i have a marble that is at absolute zero, and it's sliding across a slab of ice that is absolute zero. would there ever be any friction caused?

∫[x^2ydx + (x^2 - y^2)dy]

the first path is y=x^2 (0,0)(2,4).

so:
x = t
y = t^2
dx = dt
dy = 2tdt
0
∫(t^4 + 2t^3 - 2t^5)dt limits:{0,2}

the second path is y=2x. 0
so:
x=t
y=2t
dx = dt
dy = 2dt

so:
∫(2t^3 - 6t^2)dt limits:{0,2}

for the first one i get -104/15
and the second i get -8

they should be the same right?
did i mess up somewhere? or did you get the same answer?

Can you please help me with the following problem?
I have four masses connected by massless rigid rods so that they form the square in xy plane (each rod has length 10cm). I need to to find the moment of inertia about an axis that passes through the mass positioned at the lower left vertex of the square and perpendicular to the page. The mass at that point is 100g and all other masses are 200g.
I have a feeling that this should be very simple but all I've got is the center of mass - (5.7cm, 5.7cm) using the coordinate system with the origin at that lower left corner, and (0,10), (10, 0) and (10, 10) as the coordinates of other masses.I have the final solution but I really need the procedure how to get there.
Thanks for any help!
