4/(3Power[2(-2)+3, (3)^-1]) I get -(4/3) (-1)^(2/3) in Mathematica but only -4/3 on my calculator. N[Sec[8/(8 Sqrt[2])]]/Degree to get Cos^-1 of 8/(8 Sqrt[2]) and it gives me 75 deg instead of 45... I'm not sure what I'm doing wrong, I tried in Wolfram Alpha and it gives me the same thing. Thank you. -Francis
