#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
