whether the dependence of the two real numbers x 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.
