Cp300 The Simpliest Thing Seems No Such
Posted 06 May 2004 - 07:31 PM
We knows that ((a^(1/n))^1/m) is equal to a^(1/n*m), well, when i enter the expresion in symbolic mode (Using the 2D Keypad) the CP300 show ((a^(1/n))^1/m) as result and not the expected one a^(1/n*m). My questions are, im doing something wrong??, the CP300 have something wrong?? or the answer is just like that ??

Curious isn't it ??

I think the ClassPad cannot simplify the expression because it doesn't know whether ((a^(1/x))^(1/y) is define. As we know, in the difinition of y=a^x, a must greater than 0 and a <> 1. In this case, a must > 0 and a<>1, so the ClassPad cannot do any thing. Try with simple one : (a^x)^c, it cannot give a^(x*c).
If you try: judge((a^x)^c=a^(x*c)), it will give undefied.

b = -------
------ b * c
it represent a very basic arithmetic LAW, and the machine solve it without problem, even, a, b, c, are not defined, but when i try to do the same witn other arithmetics LAW, especially : Roots, Rationalization, Power, etc... the machine just transform the expression in other form but not show the expression in the form that such LAW demands. These examples are Elemental Arithmetics!! i no want to think that my CP300 can't solve such kind of problems !!!.
