Question
Can you help with the answers to the second question by looking at the examples in the first photo?
Check the numerical expressions below. If they are properly expressed, state so (in this case,
writing OK is enough). Otherwise, rewrite the numerical expression in a proper way.
y = (29.029+0.04) meters
v= (6.72x10-1±2.3×10²) grams
P= (9317.2± 50.5) units
a)
b)
c)

Examples:
92.81 0.3 minutes
SHOULD BE
92.8 +0.3 minutes
93 3 minutes
90 = 30 minutes
92.81 3 minutes
SHOULD BE
92.81 30 minutes
SHOULD BE
The last example is exceptional. We seldomly express such high amount of uncertainty.
For purposes of being, you may retain all the gigits displayed by your calculator until the
desired outcome of the computation is reached. As a last step you should round the
uncertainty value to one significant digit and revise the best estimate value consistently
with the uncertainty.
