Answer :
Sure! Let's solve each multiplication step-by-step in detail.
### Part (a): [tex]\(7382 \times 39\)[/tex]
We can break down the multiplication into smaller, more manageable parts.
First, break 39 into two parts: 30 and 9.
1. [tex]\(7382 \times 9\)[/tex]
[tex]\[
7382 \times 9 = 66438
\][/tex]
2. [tex]\(7382 \times 30\)[/tex]
[tex]\[
7382 \times 30 = 221460
\][/tex]
Now, add these two results together to get the final answer:
[tex]\[
66438 + 221460 = 287898
\][/tex]
So, [tex]\(7382 \times 39\)[/tex] equals [tex]\(287898\)[/tex].
### Part (b): [tex]\(6928 \times 72\)[/tex]
Similar to part (a), we can break 72 into 70 and 2.
1. [tex]\(6928 \times 2\)[/tex]
[tex]\[
6928 \times 2 = 13856
\][/tex]
2. [tex]\(6928 \times 70\)[/tex]
[tex]\[
6928 \times 70 = 484960
\][/tex]
Now, add these two results together to get the final answer:
[tex]\[
13856 + 484960 = 498816
\][/tex]
So, [tex]\(6928 \times 72\)[/tex] equals [tex]\(498816\)[/tex].
### Summary
- Part (a): [tex]\(7382 \times 39 = 287898\)[/tex]
- Part (b): [tex]\(6928 \times 72 = 498816\)[/tex]
These are the detailed steps to find the answers for both parts of the question.
