Applyop also works...

It is also possible to "dig into" the expression using applyop and only simplify a part of it:

The second command line is not strictly necessary, I use the "f" to identify what the applyop is pointing at.

I guess maple is making an additional "simplification" of the fraction... anyway, it works in this instance:

 

> 

sqrt(1/(1-b/r))

(1/(1-b/r))^(1/2)

 (1)
> 

applyop(f, [1, 1], (1/(1-b/r))^(1/2))

(1/f(1-b/r))^(1/2)

 (2)
> 

applyop(simplify, [1, 1], (1/(1-b/r))^(1/2))

(r/(r-b))^(1/2)

If you like to have few, nice output fields and do not mind messy input fields, then maybe try this:

> 

sqrt(1/(1-b/r)); applyop(simplify, [1, 1], %)

(r/(r-b))^(1/2)

If your readers prefer pure old fashion math notation and would rather not see the Maple code, then you can click View-->Show/hide content --> input

 

If you think your reader then misses the left hand side of the equation, you can do this:

> 

sqrt(``((1-b/r))^``(-1)) :% = applyop(simplify,[1,1],expand(%))

(``(1-b/r)^``(-1))^(1/2) = (r/(r-b))^(1/2)

...and then hide the input field.

Your left hand side will then have some unwanted parentheses but it still reads nicer than the input field with code.
