CAS solve equation wrong
New
The solution of the inequality
lg(x^3)+lg(x^2)+lg(x)<=3
should be 0<x<=sqrt(10), but CAS gives a negative solution and split the interval.
lg(x^3)+lg(x^2)+lg(x)<3 does not give the negative solution, but still splits the interval.
lg(x^3)+lg(x^2)+lg(x)=3 seems to be correct.
