Step-by-step explanation:
As far as I am able to observe from the statement of your question, the expression is:
![\left[[\left(3^3-7\right)\cdot \frac{5}{10}\right]+\left(\left(1+3+6+9\right)-1\right)](https://tex.z-dn.net/?f=%5Cleft%5B%5B%5Cleft%283%5E3-7%5Cright%29%5Ccdot%20%5Cfrac%7B5%7D%7B10%7D%5Cright%5D%2B%5Cleft%28%5Cleft%281%2B3%2B6%2B9%5Cright%29-1%5Cright%29)
So, lets solve this expression, which anyways would clear your concept
Considering the expression
![\left[[\left(3^3-7\right)\cdot \frac{5}{10}\right]+\left(\left(1+3+6+9\right)-1\right)](https://tex.z-dn.net/?f=%5Cleft%5B%5B%5Cleft%283%5E3-7%5Cright%29%5Ccdot%20%5Cfrac%7B5%7D%7B10%7D%5Cright%5D%2B%5Cleft%28%5Cleft%281%2B3%2B6%2B9%5Cright%29-1%5Cright%29)


Lets first solve
