If you know what a factorial is, it would be (4!-.4)/.4+4!
4!=3*2*1
5!=4*3*2*1
99!=98*97*96*........*3*2*1
_ (4/0.4)^sqrt4-4 =77 9 81 =77
(4+4)*(4+4)=8*8=64
(44 - 4)/4
77 + 7/7 = 78
To make 15 using only four 4s, we can use basic arithmetic operations such as addition, subtraction, multiplication, and division. One way to achieve this is (4 + 4 + 4) - 4 = 12 - 4 = 8. Another way is (4 x 4) - (4 ÷ 4) = 16 - 1 = 15. In total, there are several ways to make 15 using only four 4s, and it requires creative thinking and manipulation of numbers.
_ (4/0.4)^sqrt4-4 =77 9 81 =77
The answer is 4! - [(4+4)/4]
(4x4)-(4/4) = 15
4! - sqrt 4 + 4/4
4+4+4x4 by the power of 0.
(4+4)*(4+4)=8*8=64
4/.4 + 4/4 [= 10+1 = 11]
(44 - 4)/4
44/4 + 4! = 11 + (4x3x2x1) = 11 + 24 = 35
4! - sqrt(4)*sqrt(4)/4 = 23
how do i make 17 using only 2 4 6 8
77 + 7/7 = 78
