This question is related to the Question
simplify/combine doesn't see power?
Maybe many questions on forum because method is not universal. What about this one:
JA1S := (2*sqrt(2*y+3)*y+3*sqrt(2*y+3)-3*sqrt(3))/((2*y+3)^(3/2)*y);
simplify(JA1S, power, radical, symbolic); - nothing
combine(JA1S, power, radical, symbolic); - nothing
Moreover, can i somehow also reduce by y?
