Question

8 x 1000 + 4x100 + 7x10 + 1x1 + 7x1/10 + 1x1/100 + 6x 1/1000

Answer 1

To solve the expression \(8 \times 1000 + 4 \times 100 + 7 \times 10 + 1 \times 1 + 7 \times \frac{1}{10} + 1 \times \frac{1}{100} + 6 \times \frac{1}{1000}\), we will calculate each term separately and then sum them up.

1. \(8 \times 1000 = 8000\)
2. \(4 \times 100 = 400\)
3. \(7 \times 10 = 70\)
4. \(1 \times 1 = 1\)
5. \(7 \times \frac{1}{10} = 0.7\)
6. \(1 \times \frac{1}{100} = 0.01\)
7. \(6 \times \frac{1}{1000} = 0.006\)

Now, let's add all these results together:

\[
8000 + 400 + 70 + 1 + 0.7 + 0.01 + 0.006
\]

Adding them step by step:

\[
8000 + 400 = 8400
\]
\[
8400 + 70 = 8470
\]
\[
8470 + 1 = 8471
\]
\[
8471 + 0.7 = 8471.7
\]
\[
8471.7 + 0.01 = 8471.71
\]
\[
8471.71 + 0.006 = 8471.716
\]

Therefore, the final result is:

\[
\boxed{8471.716}
\]
