Answer 3

It looks like the first measurement will only have 2 significant figures in its result, since "14." only has 2 significant figures.
So, that one could be written as 2.9 * 10^2

The second measurement will also have 2 significant figures, since the multiple "12." so you could write it as 2.5 * 10^2

The third measurement would actually be closer to 2.617 than 2.7; in fact, since you can have up to 4 significant figures for that one, I would suggest you go with 2.617 rather than 2.7 anyway

Answer 4

that last one needs 4 sig figs?
