Using all numbers once:4^2 x 3 - 1 = 47[42 x 3 -1 = 47]---Simpler is 41+(2x3) = 47---To use them in that order, you could use the sqrt function1 + (23)(sqrt 4) = 47
They are 1 & 47
23 + 24 = 47
1 x 188, 2 x 94, 4 x 47.
1*47=47 Only that equation, because 47 is a prime number. >.>
47 does not have 4 prime numbers (factors or divisors).
23 + 47
How about the prime numbers of: 47+19 = 66
