A. [tex] \cdots [/tex]
B. 23
C. 12
D. 22



Answer :

To simplify the expression [tex]\( 8 + \left[4^2 - 6 + (5 + 1)\right] \)[/tex] using the order of operations, we follow these steps:

1. Parentheses and Brackets: Solve the innermost parentheses first.
[tex]\[ 5 + 1 = 6 \][/tex]
So the expression becomes:
[tex]\[ 8 + \left[4^2 - 6 + 6\right] \][/tex]

2. Exponents: Next, we handle the exponentiation.
[tex]\[ 4^2 = 16 \][/tex]
So the expression now is:
[tex]\[ 8 + \left[16 - 6 + 6\right] \][/tex]

3. Addition/Subtraction within Brackets: Evaluate the operations inside the brackets from left to right.
[tex]\[ 16 - 6 = 10 \][/tex]
Then:
[tex]\[ 10 + 6 = 16 \][/tex]
So the expression reduces to:
[tex]\[ 8 + 16 \][/tex]

4. Final Addition: Lastly, we add the remaining values.
[tex]\[ 8 + 16 = 24 \][/tex]

Therefore, the simplified value of the expression [tex]\( 8 + \left[4^2 - 6 + (5 + 1)\right] \)[/tex] is [tex]\(\boxed{24}\)[/tex].
