Answer:
![13*[4+(9-2)]=143](https://tex.z-dn.net/?f=13%2A%5B4%2B%289-2%29%5D%3D143)
Step-by-step explanation:
we have
![13*[4+(9-2)]](https://tex.z-dn.net/?f=13%2A%5B4%2B%289-2%29%5D)
step 1
Solve 

substitute
![13*[4+7]](https://tex.z-dn.net/?f=13%2A%5B4%2B7%5D)
step 2
Solve ![[4+7]](https://tex.z-dn.net/?f=%5B4%2B7%5D)
![[4+7]=11](https://tex.z-dn.net/?f=%5B4%2B7%5D%3D11)
substitute
![13*[11]](https://tex.z-dn.net/?f=13%2A%5B11%5D)
step 3
Solve 

therefore
![13*[4+(9-2)]=143](https://tex.z-dn.net/?f=13%2A%5B4%2B%289-2%29%5D%3D143)
