Learning PS - this is what I want to do and below that is what I have- any suggestions

•  
  1. List the last 50 entries in the System log using Get-WinEvent
  2. Output 2 blank lines
  3. List the last 50 entries in the Application log using Get-EventLog, sorting by Index
  4. Output 2 blank lines

Using pipes, list the entries in the Application log using Get-EventLog that were written/generated in the last 30 days, sorting by Index

get-WinEvent -log system -maxevents 50
Write-host
Write-host
get-Eventlog -log application -newest 50 | sort-object -property index
Write-host
Write-host
$ara = @(get-eventlog -log application -newest 50)
  foreach ( $element  in  $ara )
  {
$val = $element.index.ToString()

Write-Host $val
}
