Answer :
To solve the expression [tex]\(12 - 3(9)^2\)[/tex], we can follow these steps:
1. Evaluate the exponentiation:
- The expression inside the parentheses is [tex]\(9\)[/tex].
- Squaring 9 gives us [tex]\(9^2\)[/tex], which is [tex]\(81\)[/tex].
2. Multiply by 3:
- Next, we need to multiply [tex]\(81\)[/tex] by [tex]\(3\)[/tex], which yields [tex]\(3 \times 81 = 243\)[/tex].
3. Perform the subtraction:
- Now, subtract [tex]\(243\)[/tex] from [tex]\(12\)[/tex], which can be written as:
[tex]\[12 - 243 = -231\][/tex]
So, the numerical result is [tex]\(-231\)[/tex].
Given this careful, step-by-step calculation, the answer to the given expression [tex]\(12 - 3(9)^2\)[/tex] is [tex]\(-231\)[/tex].
Regarding the coordinate [tex]\((2,3)\)[/tex], since it is not directly related to the previous calculation and it's a distinct question, the coordinate [tex]\((2,3)\)[/tex] simply refers to a point on the Cartesian plane where the x-coordinate is [tex]\(2\)[/tex] and the y-coordinate is [tex]\(3\)[/tex].
However, it seems this part of the question might have been mixed with the previous numerical problem. If there's a specific context or figure associated with identifying this point, please provide more details for precise assistance.
