I think there's some disagreement over the associativity of exponentiation. The 65 Notes article suggests it's right associative  i.e. 2^1.8^1.6^1.4^1.2 = 2^(1.8^(1.6^(1.4^1.2)))  which the 35's x^y is particularly well suited to handle. That is, of course, most definitely not equal to 2^(1.8*1.6*1.4*1.2). If we assume the exponents are leftassociative, then you are correct. It seems like TI treats it as leftassociative (28.6) according to my 58C, 85, and 84 Plus, and Casio changed from leftassociative to rightassociative (9.72) at some point: my fx7000G is leftassociative, and the fx5800P and fx991EX both display the operator as ^( in line I/O mode, clearly showing the right associativity.
