## great! How did you do...

great! How did you do it?

What do those "

```op(1,expr)*op(3,expr)"

etc. mean?

I have more expressions like this and I would like to apply your method to make the denominator as simple as possible...

Thanks a lot!

## The numerator has factors...

The numerator has factors g^(1), and g^(2/3),

the denominator has g^(2/3),

if I can get rid of the g^(2/3) on the denominator, then only g^(1/3) will remain on the numerator,

that's exactly what I want.

I just don't want any g on the denominator.

Thanks!

## okay, here you go....

Okay,

this is the result after using the command "simplify",

but as you could see,

-(1/12)*(-g*vb-g+z*g-g^(2/3)*z+g^(2/3)*vb)*(g^(1/3)+1)^5/g^(2/3)

there is a common factor g^(2/3) on both the numerator and demoninator.

However I would like to remove such a common factor and therefore make the denominator as reduced as possible.

Any thoughts?

Thanks a lot!
