Try the .simplify_radical() method.

Is there a way to simplify sqrt(some_unit_of_measurement^2) without knowing what's in the expression? Often a chain of computations will lead to a result like the following:

7.5 * sqrt(units.length.meter^2)

I would sage to simplify the units and give me

7.50000000000000*meter

but haven't found symbolic expression ops to get past this output:

7.50000000000000*sqrt(meter^2)
