Step-by-step explanation:
Given the expression
![3^2\:+\:\left(21\:-\:9\right)\:\times \:6\div 2](https://tex.z-dn.net/?f=3%5E2%5C%3A%2B%5C%3A%5Cleft%2821%5C%3A-%5C%3A9%5Cright%29%5C%3A%5Ctimes%20%5C%3A6%5Cdiv%202)
Follow the PEMDAS order of operations
![3^2\:+\:\left(21\:-\:9\right)\:\times \:6\div 2](https://tex.z-dn.net/?f=3%5E2%5C%3A%2B%5C%3A%5Cleft%2821%5C%3A-%5C%3A9%5Cright%29%5C%3A%5Ctimes%20%5C%3A6%5Cdiv%202)
calculate within parentheses ![\:(21-9)=12](https://tex.z-dn.net/?f=%5C%3A%2821-9%29%3D12)
![=3^2+12\times \:6\div \:2](https://tex.z-dn.net/?f=%3D3%5E2%2B12%5Ctimes%20%5C%3A6%5Cdiv%20%5C%3A2)
calculate exponents
![=9+12\times \:6\div \:2](https://tex.z-dn.net/?f=%3D9%2B12%5Ctimes%20%5C%3A6%5Cdiv%20%5C%3A2)
Multiply and divide (left to right)
![=9+36](https://tex.z-dn.net/?f=%3D9%2B36)
Add and subtract (left to right) ![12\times \:\:6\div \:\:2=36](https://tex.z-dn.net/?f=12%5Ctimes%20%5C%3A%5C%3A6%5Cdiv%20%5C%3A%5C%3A2%3D36)
![=45](https://tex.z-dn.net/?f=%3D45)
Thus,
![3^2+\left(21-9\right)\times \:6\div \:2=45](https://tex.z-dn.net/?f=3%5E2%2B%5Cleft%2821-9%5Cright%29%5Ctimes%20%5C%3A6%5Cdiv%20%5C%3A2%3D45)
