Pass build variables to powerhshell inline script in Azure DevOps
To get the build variables with inline power shell script, you can try to use following syntax $env:variable:
$env:myvariable
The build variable:
The build result:
Note:At this moment, the value of nested variables (like $(myvariable$(Build.SourceBranchName))) on build variables table are not yet supported in the build pipelines.
Hope this helps.

here's what's working for me:
$(variableName)
for example built-in variable called Build.BuildNumber can be accessed like so:
$(Build.BuildNumber)
full example with format function:
- task: AzurePowerShell#3
displayName: UpdatePrereq
inputs:
azureSubscription: ${{ parameters.azureSubscription }}
ScriptType: InlineScript
Inline: |
${{ format('. $(Build.Repository.LocalPath)\scripts\_helpers.ps1
Update-DeploymentPrereq -resourceGroup {1} -location {3}
Update-Prereq -pathSuffix {0} -pathBase $(Build.Repository.LocalPath) -resourceGroup {1} -buildId $(Build.BuildNumber) -paramFile {2}
Update-DeploymentConcurrency -resourceGroup {1} -buildId $(Build.BuildNumber)',
parameters.buildDir, parameters.resourceGroupName, parameters.paramFile, parameters.location ) }}
azurePowerShellVersion: LatestVersion

If you need to use nested variables you can use something like this:
$name = "CONNECTIONSTRING_$(Agent.MachineName)"
$val = [System.Environment]::GetEnvironmentVariable($name)
And then you get the value of the variable ConnectionString.MACHINENAME
