Error in simplifying a function
Hi,
In helping my son with some simple algebra homework (he was duly impressed with the Prime), we ran across one problem that would not simplify further (but was correct) and another that simplified incorrectly. Case 1: (3) NTHROOT ((4) NTHROOT (64*z^18*w^6)) returns: (w^6*z^18)^(1/12)*sqrt(2) which is correct, but I could not find and command to simplify to: sqrt(w)*z^(3/2)*sqrt(2) Case 2: (4) NTHROOT (100*a^2+300*a*b+225*b^2) returns: √(-2*a-3*b)*√5 which is incorrect. It should be sqrt(2*a+3*b)*sqrt(5) I am using the latest release under both the real (revision C) and virtual (PC) calculators. Any ideas? Thanks and take care, Steve |
