(2x2)2
It is: 16 or as 2*2*2*2 = 16
(3 + 1)2 = 16
It is: 2^4 = 16
16=4*4=2*2*2*2=2**4
2 * 2 * 2 * 2 It's not possible to make 16 without using the same numbers twice or without using whole numbers.
to me i think 2 to the power of 2x2 to the power of 2 * * * * * 16 = 24
(4 + 3 + 1) x 2 = 16
1, 2, 4, 8, 16
3-1=2 then 2x2x4=16.
How about: 2*(1+3+4) = 16
(4+3+1)x2=16
16
