I think the answer is 2^ 5 .
2^ (4-1) = 2^ 3
2^(4-1)^ 2= (2^3)^2 = 2^6
Denominator evaluates to 2 . hence the answer is 2^5
2^ (4-1) = 2^ 3
2^(4-1)^ 2= (2^3)^2 = 2^6
Denominator evaluates to 2 . hence the answer is 2^5
2^(4-1)^2 = 2^9malolakrupa wrote:I think the answer is 2^ 5 .

but
[2^(4-1)]^2= 2^6
Let me know if you think otherwise.
