Question

How do you write `129g/ 29.2 mL` in scientific notation?

Answer 1

`5.8636bar(36)gcolor(white)(.)mL`

Explanation:

Write as `129/29.2 gcolor(white) mL`

`129-:29.2 =58.636363....`

A terminating or repeating decimal indicates that this value may be written in fractional form, which is precise. `.636363..` is not precise. However, we are instructed that the answer is to be in scientific form which is decimal so we have no choice regarding format.

`58.636363.." is the same as "5.8636363.. xx10`

So the answer is: `5.8636bar(36)` where the bar over the last 36 indicates that this repeats indefinitely
