Answer:
To simplify the expression 8x1/10+2x1/100+3x1/1000, we can start by finding a common denominator for the fractions. In this case, the common denominator is 1000 since 10, 100, and 1000 can all be evenly divided by 1000.
Next, we need to convert the fractions to have the same denominator. To do this, we multiply the numerator and denominator of each fraction by the same factor that will make the denominator equal to 1000.
For the first fraction, 1/10, we multiply the numerator and denominator by 100 to get 100/1000.
For the second fraction, 1/100, we multiply the numerator and denominator by 10 to get 10/1000.
And for the third fraction, 1/1000, we already have 1/1000.
Now, we can add the fractions together: 8(100/1000) + 2(10/1000) + 3(1/1000).
Simplifying each part of the expression, we get: 800/1000 + 20/1000 + 3/1000.
Adding the fractions together, we get: 823/1000.
So, the expression 8x1/10+2x1/100+3x1/1000 is equal to 823/1000.
In standard form, the expression is written as 0.823.
In word form, the expression can be read as "eight hundred twenty-three thousandths."
