Is there any way to do the following without creating the object $obj?

$obj = New-Object System.Security.Principal.NTAccount("Students") ; $obj.Translate([System.Security.Principal.SecurityIdentifier]).Value

I have tried to pipe, like this:

New-Object System.Security.Principal.NTAccount("Students") | $_.Translate([System.Security.Principal.SecurityIdentifier]).Value

but got following error:

Expressions are only allowed as the first element of a pipeline.
At line:1 char:128
+ New-Object System.Security.Principal.NTAccount("Students") | $_.Translate([System.Security.Principal.SecurityIdentifi
er]).Value <<<<
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException
    + FullyQualifiedErrorId : ExpressionsMustBeFirstInPipeline

Thanks in advance!

If you want to stick to using the pipeline, use the ForEach-Object cmdlet.

 New-Object System.Security.Principal.NTAccount("Students") | ForEach-Object {
