Hello watcher2, try: (((((3^(1/2))^(1/2))^(1/2))^(1/2))^(1/2))/(6^(1/2)) Out: 1/(Sqrt[2]*3^(15/32)) You can see what happened: 1st: 6^(1/2) = 2^(1/2)*3^(1/2); 2nd: subtraction of the 3's exponents (1/2)^5 - 1/2 = 1/32 - 16/32 = - 15/32. MATHEMATICA does these straightforward simplifications without you having to invoke Simplify[]. Best regards, Matthias Bode Sal. Oppenheim jr. & Cie.
