i got a set of roots of nonlinear equation by fslove method.e.g.

y1:=a^4+b-3=0;

y2:=a^3+b^2+2=0;

fsolve({y1, y2})

⇒{a = -1.402752934, b = -.8719054433}

i got roots value of the equation,but i want to continue to use direcly the float values of 'a' and 'b' in my program,but i couldnt ues them by some methods since 'a' and 'b' didnt seem to be assigned.so i had to write the values in a text file,then read the values back to my program and use them. if u hv gud idea or gud method to solve that,tell me please!!thank u!
