whether the dependence of the two real numbers a and y, in 
these two last equations, on the two real numbers a and b, 
cannot be expressed by the help of the real inverses of some 
new real and rational or even transcendental functions of 
single real variables; or, (to express the same thing in a 
practical, or in a geometrical form,) to inquire whether the 
two sought real numbers cannot be calculated by a finite 
number of tables of single entry, or constructed by the help 
of a finite number of curves: although the argument of Abel 
excludes all hope that this can be accomplished, if we con- 
fine ourselves to those particular forms of rational functions 
which are connected with the extraction of radicals.
