Sure, let's break down each expression step by step to find the final results.
### Expression 1: [tex]\(13 \times 12 \times 11 + 12\)[/tex]
1. First, multiply the numbers 13, 12, and 11 together:
[tex]\[
13 \times 12 = 156
\][/tex]
[tex]\[
156 \times 11 = 1716
\][/tex]
2. Then, add 12 to the result of the multiplication:
[tex]\[
1716 + 12 = 1728
\][/tex]
So, the result of the first expression [tex]\(13 \times 12 \times 11 + 12\)[/tex] is 1728.
### Expression 2: [tex]\(8 \times 7 \times 6 \times 5 + 5\)[/tex]
1. First, multiply the numbers 8, 7, 6, and 5 together:
[tex]\[
8 \times 7 = 56
\][/tex]
[tex]\[
56 \times 6 = 336
\][/tex]
[tex]\[
336 \times 5 = 1680
\][/tex]
2. Then, add 5 to the result of the multiplication:
[tex]\[
1680 + 5 = 1685
\][/tex]
So, the result of the second expression [tex]\(8 \times 7 \times 6 \times 5 + 5\)[/tex] is 1685.
### Summary:
- The value of [tex]\(13 \times 12 \times 11 + 12\)[/tex] is 1728.
- The value of [tex]\(8 \times 7 \times 6 \times 5 + 5\)[/tex] is 1685.
