Dear maxima users I found the following example display2d:false$ logconcoeffp: 'logconfun$ logconfun(m) := featurep(m,integer) or ratnump(m)$ logcontract(1/2*log(x)); which leads to log(sqrt(x)) Is there something similar to transform x^(5/2) to sqrt(x^5)? Reason: To continue processing maxima's output the sqrt-form would be nicer. Thank you.
