Answer 1

3.

Step-by-step explanation:

Hello,

In this case, considering the given number:

`2.30x10^5`

We can see that it does not have zeros to left of the first nonzero digit which is 2, therefore, we just have to consider the 2, 3 and 0 as significant figures because the right-handed zeros are actually considered. Hence, such measurement has 3 significant figures.
