( (3x3) +3 ) /3=4
As a solution to the four fours problem (using the number four no more than four times to come up with the solution, 31 is equal to (4!+4)/4+4!
How about: 44-(4/4) = 43
In infinitely many ways. However, if you want powers of positive integers only, then you can express 64 as a power of 2, 4, 8 and of 64 itself.
4/.4 + 4/4 = 10 + 1 = 11.
Four
4 + 4 + (4/4).

It looks like you're asking what is the largest 4-digit number which has four 4's for digits - with a four digit number using four 4's, there is only one such number: 4444. Maybe I'm not understanding the wording of your question.
Four factorial plus the square root of four minus (four divided by four) 24 + 2 - 1 = 25
145.992 using only four significant figures is 146.0
4*6+1
21,600 using only four significant figures is still 21,600.
In infinitely many ways. However, if you want powers of positive integers only, then you can express 64 as a power of 2, 4, 8 and of 64 itself.
