Excel ...Exact function gives "False" result.... puzzle

[#1]

I tried to compare two text strings to see they are the same. They have the same cell format, font style, size, and colour, yet the result of comparison is "False",
Am I misunderstanding the "Exact" function?

You aren't.
I just did a quick check and adding a trailing blank to one of the text strings makes the answer false - might be worth checking

[#3]

You were right! LEN function gives 14 and 9, but how does one remove trailing blanks , they being invisible?

[#4]

put the cursor at the end of the text and press backspace 
unless you mean remove trailing blanks automatically then use this function
