Hello! My name is Saeed and i'm studying physics. I have a problem which ihope someone can help me with it. I have an equation .001422409738*R^(73/80)*(R^(1/2)-1)^(-13/40) == .04 i'm using the Solve function in Mathematica 3.0 to solve it for R, but it calculats endlessly and takes very long time. the question is that is there any way to optimize this equation or using another function in Mathematica 3.0 to make it faster to calculate? Regards
