Arturas,
Definitely the same problem with Version 5.0.0 on Windows98. It's a bug.
But working with the denominator first...
expr = 5*(-7 + 4*Sqrt[3])^3*
(1/2 - 1/(2*(-7 + 4*Sqrt[3])^2))*
(((-384 + 224*Sqrt[3])*(3/2 + 2*Sqrt[3] +
1/(2*(-7 + 4*Sqrt[3]))))/(-(1/2) +
1/(2*(-7 + 4*Sqrt[3])^2)))^(3/2);
Simplify[expr]
1/%
-1280*I*Sqrt[56451 - 32592*Sqrt[3]]*(-7 + 4*Sqrt[3])*
(-97 + 56*Sqrt[3])
I/(1280*Sqrt[56451 - 32592*Sqrt[3]]*(-7 + 4*Sqrt[3])*
(-97 + 56*Sqrt[3]))

Dear Group,
Just try to evaluate this expression
1/(5*(-7 + 4*Sqrt[3])^3*(1/2 - 1/(2*(-7 + 4*Sqrt[3])^2))*(((-384 +
224*Sqrt[3])*(3/2 + 2*Sqrt[3] + 1/(2*(-7 + 4*Sqrt[3]))))/(-1/2 +
1/(2*(-7 + 4*Sqrt[3])^2)))^(3/2))
in 5.0. on linux box I receive $IterationLimit::"itlim" message.
Is it repeatable?
Sincerely. Arturas Acus
