i have a problem



HI!
i want to  solve this system:
?
 solve([1/(c0+c1*c0*r)^2=0.0178,  (l*c1*r*c0/(c0+c1*c0*r)^2) =0.182,   (2*l*c1*c0*r-c1*r-l*c0-r*c0)/(c0+c1*c0*r)^2=0.00742,   (1/(2*3.14*l*c1*r*c0))*sqrt(l*c0*(2*c1*r-1)-r*(c1+c0)-1)=2.523], [l,r,c0,c1]);

the answer of maxima is:


rat: replaced -0.0178 by -89/5000 = -0.0178
?rat: replaced -0.182 by -91/500 = -0.182
?rat: replaced -0.00742 by -371/50000 = -0.00742
?rat: replaced -2.523 by -2523/1000 = -2.523
?rat: replaced 0.15923566878981 by 25/157 = 0.15923566878981

Could you help me please?

thank you
