Final answer:
To find the answer to the expression 1x3x4x6+1, we need to apply the order of operations, also known as PEMDAS. The correct answer is 73.
Step-by-step explanation:
To find the answer to the expression 1x3x4x6+1, we need to apply the order of operations, also known as PEMDAS. First, we multiply 1 and 3, getting 3. Then, we multiply 3 and 4, getting 12. Finally, we multiply 12 and 6, obtaining 72. Finally, we add 1 to 72, resulting in the answer of 73. Therefore, none of the given options a) 71, b) 81, c) 61, or d) 91, are correct.
