Answer:
1. 5417.412
2. 401.13
Step-by-step explanation:
1. First, rewrite
[tex]5\times 10^3+4\times 10^2+1\times 10^1+7\times 10^0+4\times \dfrac{1}{10^1}+1\times \dfrac{1}{10^2}+2\times \dfrac{1}{10^3}[/tex]
as
[tex]5\times 1000+4\times 100+1\times 10+7\times 1+4\times 0.1+1\times 0.01+2\times 0.001[/tex]
So, this is
[tex]5000+400+10+7+0.4+0.01+0.002\\ \\=5417.412[/tex]
2. First, rewrite
[tex]4\times 10^2+1\times 1 \dfrac{1}{10^1}+3\times \dfrac{1}{10^2}[/tex]
as
[tex]4\times 10^2+1\times 1 +1\times \dfrac{1}{10^1}+3\times \dfrac{1}{10^2}[/tex]
This is
[tex]4\times 100+1\times 1+1\times 0.1+3\times 0.01[/tex]
So, this is
[tex]400+1+0.1+0.03\\ \\=401.13[/tex]
