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.

How do you make 77 with 4 fours?

[√(4/.4*)]^4 - 4 = [√9]^4 - 4 = 3^4 - 4 = 81 - 4 = 77 N.B. the denominator within the square root is meant to be 0.4 recurring, which is written with a dot above the 4 but I am not able to do this. 0.44444...... = 4/9 Also, if you do (4-40)3 - 4

How do you do the four fours challenge?

To do the Four Fours challenge, you use exactly four fours, no more and no less and try to find every number form 1-100. You can use 4!, square root, 4/4, exponential, +,-,*, and division(fraction notation) For example 9 is: 4+4+4/4


What is 77 in four 4s?

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.
