Answer:
There are many possible solutions. For example,
(2^3)^4 = ((2^5)^12)/((2^6)^8) = 2^10 x 2^2 = (2^19)/(2^7)
(2^2)^5 = ((2^6)^11)/((2^7)^8) = 2^1 x 2^9 = (2^20)/(2^10)

Step-by-step explanation:
X=-x^2+x-5
12 1/2 (12x2+1)= 25/2
25/2 x 8/5 (we have to multiply8/5, not 5/8), so =200/10=20
answer is 20
