Question

7 x 8 ÷ 2 x 14 + 3² =?

• A. 9
• B. 401
• C. 13
• D. 10

Answer 1

Answer:

B. 401

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
