Need a formula that pulls the latest date from a range that have dates in text format

I have a range of cells that have dates but in a text format. I cannot change the format to a date format. I need a formula that basically pulls the latest date from the range of cells that have dates in a text format. See the file attached. Thank you for helping in advance.

Try this:
=TEXT(E5,"mm/dd/yyyy")

Sorry, I misinterpreted your request. Reviewing now.

Try this:

{=MAX(VALUE(E3:E5))}

Note: this is an array formula, so when you enter this formula, instead of hitting enter, you need to hit shift ctrl enter, which gives you the curly brackets.
