Simplifying a product of radical expressions: Univariate

[parisse]

to nerdtopia: simplify returns 5*sqrt(2)*sqrt(y)*y^4, I don't understand why you consider 5*sqrt(2*y)*y^4 to be more simplified. I don't think you can collect sqrt(2) and sqrt(y), because the sqrt do not apply on the same kind of objects.

to Aries: since you are (almost?) always giving comments for the TI Nspire, I wonder if you observed that the forum title is "HP Prime"? I believe people here are primarily expecting answers and comments for the HP Prime, not for the TI Nspire, otherwise they would go to TI forums. I believe that it's not wrong to make sometimes a comparison with other calculators, but frankly speaking, it's irritating to see (almost?) all your posts that never give additional value about the HP Prime (and always seems to be a variation of "it's so much better with the Nspire").
