Mathematics
1 answer:
salantis [7]3 years ago
5 0

Answer:

2

Step-by-step explanation:

4.0 has 2 significant digits.

The zeros after a non zero number are significant.

Any non zero number is significant.

0.004 has 1 significant digit.

4000 has 4 significant digits.

In your case 4.0 × 10^3 there is an exception because it is in scientific notation. So there are 2 significant digits.

hope this makes sense.
