Question

To the correct number of significant figures: 865 + 665 =

Answer 1

Answer:

3

Explanation:

Let's note that the below can be considered as a significant figure;

*Any zero between non-zero digits

*Non-zero digits

*Any trailing zero when in a decimal number

So considering the given problem, if add the two numbers, we'll have;

$865+665=1530$

We can see that 1530 has a trailing zero and it's not a decimal number, therefore the correct number of significant figures is 3.
