use the digits 1,2,3, and 4 to write a number in scientific notation that is close to .001

this was in a 7th grade algebra book... what? is this even possible without the use of 0?

1.24*10^-3 = .00124

R+3+2r=-21

estimate:42.9*7.84=

use this equation to complete the table m = 100 - k

Yes, it is possible to write a number in scientific notation using the digits 1, 2, 3, and 4 that is close to 0.001. Scientific notation is a way of writing numbers as the product of a decimal number and a power of 10.

To write a number in scientific notation, we need to move the decimal point so that there is only one digit to the left of it. In this case, we want to get as close as possible to 0.001 using the given digits.

The digit 1 is the closest to 0.001, so we can start with that as the first digit. Next, we need to determine the power of 10 that will shift the decimal point appropriately.

To get a number close to 0.001, we need to move the decimal point three places to the left. This means we will have a negative exponent of 10.

Putting it all together, the number in scientific notation using the digits 1, 2, 3, and 4 that is close to 0.001 would be:

1.234 × 10^-3
