Answer:
B. 401
Read Explanation:
The final answer to the expression $7 \times 8 \div 2 \times 14 + 3^2$ is 401.
Given Expression:
$7 \times 8 \div 2 \times 14 + 3^2$
Step 1: Solve the Order / Exponent ($3^2$)
Calculate the square of 3 first:
$$3^2 = 3 \times 3 = 9$ Now the expression becomes:
$7 \times 8 \div 2 \times 14 + 9$
Step 2: Division ($8 \div 2$)
When multiplication and division are adjacent, always solve them in order from left to right. The first operation encountered from the left is the division:
$8 \div 2 = 4$ Now the expression becomes:
$7 \times 4 \times 14 + 9$
Step 3: First Multiplication ($7 \times 4$)
Continue working through the remaining multiplication terms from left to right:
$7 \times 4 = 28$Now the expression becomes:
$28 \times 14 + 9$
Step 4: Second Multiplication ($28 \times 14$)
Complete the final multiplication step:
$28 \times 14 = 392$
Now the expression becomes:
$392 + 9$
Step 5: Final Addition ($392 + 9$)
Add the numbers to find the total:
$392 + 9 = \math
