Answer:
9
Step-by-step explanation:
Given: Subtract 9 from 10. Multiply this difference by 3, square this product.
Now, lets simplify it.
![[(10-9)\times 3]^{2}](https://tex.z-dn.net/?f=%5B%2810-9%29%5Ctimes%203%5D%5E%7B2%7D)
Using PEDMAS rule to solve it
First working on Parenthesis
= ![[(1)\times 3]^{2}](https://tex.z-dn.net/?f=%5B%281%29%5Ctimes%203%5D%5E%7B2%7D)
Opening the parenthesis
= ![[1\times 3]^{2}](https://tex.z-dn.net/?f=%5B1%5Ctimes%203%5D%5E%7B2%7D)
= ![[3]^{2}](https://tex.z-dn.net/?f=%5B3%5D%5E%7B2%7D)
= 
∴ Answer is 9.
