The stairs on the outside of my home are made of concrete the previous owners had glued carpet to them it looks like more than once because of amountof glue on the concrete how can I get the glue off or can I just put something over it to make it look good and not carpet .

A lot depends on what type of glue was used. Tell us the color and is it brittle or slightly soft. Chances are you will never get it all off. Do you have a heavy duty pressure washer or can you rent one. The glue might be softened with heat or a solvent.

I agree with Ballenger, a solvent that will break up that glue. Try this one or something similar.

A wire wheel or sandblasting might work if the pressure washer doesn't do it.
