The correct simplification of the expression 12 “:” 3 times 4-1+2^3 is not listed in the options provided. Following the order of operations, the expression simplifies to 23, which is not among the choices given. The correct option is 1
The student is asking for the correct simplification of the mathematical expression 12 “:” 3 times 4-1+2^3. This is a problem involving various operations such as division, multiplication, subtraction, and exponentiation. To solve this expression correctly, one must follow the order of operations, commonly remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). Let’s simplify the expression:
Calculate the exponent: 23 = 2 times 2 times 2 = 8
Perform division and multiplication from left to right: 12 “:” 3 = 4 and then 4 times 4 = 16
Finally, perform the subtraction and addition: 16 – 1 = 15, and then 15 + 8 = 23.
Therefore, the simplified expression is 23. Looking at the options provided by the student, none of them are correct. There might be a typo in the question. The correct simplification should be listed as another option representing the number 23. The correct option is 1
