Best Answer

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.

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.
