Let's go through the problem step by step to find the numerical values of the expressions given:
1. For the first expression:
[tex]\[
3 \cdot \left(1 \times 10^{-3}\right)
\][/tex]
We multiply 3 by [tex]\(1 \times 10^{-3}\)[/tex]:
[tex]\[
3 \cdot 0.001 = 0.003
\][/tex]
2. The second expression is:
[tex]\[
2 \times 10^{-3}
\][/tex]
This is simply [tex]\(2 \times 0.001\)[/tex]:
[tex]\[
2 \times 0.001 = 0.002
\][/tex]
3. The third expression is:
[tex]\[
3 \times 10^{-3}
\][/tex]
This is:
[tex]\[
3 \times 0.001 = 0.003
\][/tex]
4. The fourth expression is:
[tex]\[
5 \times 10^{-3}
\][/tex]
This is:
[tex]\[
5 \times 0.001 = 0.005
\][/tex]
5. The fifth expression is:
[tex]\[
4 \times 10^{-3}
\][/tex]
This is:
[tex]\[
4 \times 0.001 = 0.004
\][/tex]
So, after evaluating all the expressions, we have the following results:
[tex]\[
[0.003, 0.002, 0.003, 0.005, 0.004]
\][/tex]
These are the numerical values for the given expressions.
