Final answer:
To write the expression 9×1±4 1/100±8 1/1000 in standard form, we need to rewrite it in scientific notation.
Step-by-step explanation:
To write the expression 9×1±4 1/100±8 1/1000 in standard form, we need to rewrite it in scientific notation. Scientific notation is a way to represent numbers as a product of a decimal number (between 1 and 10) and a power of 10.
- 9×1 can be written as 9.
- 4 1/100 can be written as 0.04.
- 8 1/1000 can be written as 0.008.
Putting it all together, the expression 9×1±4 1/100±8 1/1000 in standard form is equal to 9×1 - 4 1/100 - 8 1/1000 = 9 - 0.04 - 0.008.
