The only solution that I have ever seen uses some notation that is not so commonly used, namely a bar over 4 to mean the infinitely repeating decimal
.44444... which is 4/9 . So, if x = 4/9 is written with one four,
then sqrt(4/x) 4 - 4 uses four fours and equals 77
since 4/x = 4 * 9/4 = 9 and
sqrt(9)4 - 4 = 34 - 4 = 81 - 4 = 77.

How do you get 77 out of 4 fours?
To achieve the number 77 with four fours, the solution is as follows: sqrt(4/.4)4 - 4 Instead of the second four being equal to four tenths, place a dot over the top to indicate it being equal to four ninths.
