If you do in fact mean 
(as opposed to one of these being the derivative of 
at some point), then integrating twice gives
From the initial conditions, we find
Eliminating 
, we get
![C_1 = -\dfrac{\ln(6)}5 = -\ln\left(\sqrt[5]{6}\right) \implies C_2 = \ln\left(\sqrt[5]{6}\right)](https://tex.z-dn.net/?f=C_1%20%3D%20-%5Cdfrac%7B%5Cln%286%29%7D5%20%3D%20-%5Cln%5Cleft%28%5Csqrt%5B5%5D%7B6%7D%5Cright%29%20%5Cimplies%20C_2%20%3D%20%5Cln%5Cleft%28%5Csqrt%5B5%5D%7B6%7D%5Cright%29)
Then

Answer: 120,000
Step-by-step explanation:
Let the question mark = x
x*1/100 = 1200
Multiply by 100 on both sides:
x = 1200*100
x = 120,000
You do (3)*(3)*(3)= 27
Then you do (4)*(4)*(4)= 64
Now you add them 27*64= 1728
I know this is correct because I am doing the same thing in my math class.
Hope this helps. :)
