How do I write a command in a .batch file written in NOTEPAD to run a powershell command?

How do I write a command in a .batch file written in NOTEPAD to run a powershell command?

Example:

powershell -Command "& {Update-Help;}"

would this be a correct command to put in a .batch file to update help information in powershell.

All I want to know is how to write a windows powershell command in a .batch file.
