    [bugfix] fix elusive bug in quo, rem,...
    
    The power of two rational numeric objects needs not be rational. As a
    result, some care is required when transforming (b^e)*l -> (b*l^(1/e))^e
    for some rational e and l. This is a common transformation in order to
    convert a polynomial over Q into a polynomial over Z when computing
    their quotient, remainder, etc. Failure to be careful can potentially
    introduce spurious non-rational numbers into rational polynomials and
    make those operations fail. This patch avoids this transformation when
    l^(1/e) is not a rational number.
