Question

What is `56.2 xx 9.2057` in significant digits?

Answer 1

See explanantion

Explanation:

You have not defined the level of significance. For example 'first significant figure'.

I would suggest that for any significant figure calculation you would multiply the whole thing first then select the figure from the product. this reduces rounding error. Unless instructed otherwise that is!

The product is 517.36034

From this the most significant figure is 500.

Suppose you had to select the two most significant figures before you multiply then you have:

`56xx9.2= 515.2` which has combined the two levels of significance. Again it depends on the instructions given.
