4. Calculate the following.

**Example:**

[tex]
\[ 3432 \times 26 \]
\]

[tex]
\[
\begin{array}{r}
3432 \\
\times \quad 26 \\
\hline
20592 \quad \longrightarrow \quad 6 \times 3432 \\
= 6 \times (3000 + 400 + 30 + 2) \\
= 18000 + 2400 + 180 + 12 \\
= 20592 \\
+ 68640 \quad \longrightarrow \quad 20 \times 3432 \\
= 20 \times (3000 + 400 + 30 + 2) \\
= 60000 + 8000 + 600 + 40 \\
= 68640 \\
\underline{89232} \\
\end{array}
\]

**a.** [tex]\[ 7382 \times 39 \][/tex]

**b.** [tex]\[ 6928 \times 72 \][/tex]

Answer :

Sure! Let's solve the given multiplications step-by-step:

a. [tex]\(7382 \times 39\)[/tex]

1. Split [tex]\(39\)[/tex] into [tex]\(30 + 9\)[/tex].
2. Compute [tex]\(7382 \times 9\)[/tex]:
[tex]\[
7382 \times 9 = 66438
\][/tex]
3. Compute [tex]\(7382 \times 30\)[/tex]:
[tex]\[
7382 \times 30 = 221460
\][/tex]
4. Add the two results together:
[tex]\[
66438 + 221460 = 287898
\][/tex]

So, [tex]\(7382 \times 39 = 287898\)[/tex].

b. [tex]\(6928 \times 72\)[/tex]

1. Split [tex]\(72\)[/tex] into [tex]\(70 + 2\)[/tex].
2. Compute [tex]\(6928 \times 2\)[/tex]:
[tex]\[
6928 \times 2 = 13856
\][/tex]
3. Compute [tex]\(6928 \times 70\)[/tex]:
[tex]\[
6928 \times 70 = 6928 \times 7 \times 10 = 48596 \times 10 = 485960
\][/tex]
4. Add the two results together:
[tex]\[
13856 + 485960 = 499816
\][/tex]

So, [tex]\(6928 \times 72 = 498816\)[/tex].

Here are the final results:
- [tex]\(7382 \times 39 = 287898\)[/tex]
- [tex]\(6928 \times 72 = 498816\)[/tex]
