Question

Which of these numbers has five significant numbers?

Answer 1

Answer:

c

Step-by-step explanation:

A has 9 sig digits. Every digit counts including the 4 zeros, because 3 digits follow them. Even if the 345 were not there, there still are 6 sig digits.

B. Those two trailing zeros mean something. They are guaranteed place holders. This number has 7 sig digs.

D. Depends on who teaches this. 5 without a period at the end means that the number is exactly 5 -- or that's the rule when I was teaching.

The answer is C, believe it or not. Again, those zeros are place holders. They are guaranteed to be accurate. This is a question to look at carefully.

Answer 2

Hello There!

1.0000 has 5 significant digits.

The zeros at the end of a decimal are significant.

Hope this helps you!
