Question

How many significant numbers are there in 0.0004529

Answer 1

Answer: four significant numbers

Explanation:

The number 0.0004529 has four significant numbers because the number of numbers from the 1st number on the left, other than zero, to the last number is 4 (4, 5, 2, 9)

Answer 2

Answer: 4

Step-by-step explanation: Since there is no digit in the ones-place, you can already remove the rest of the 0s since they are also not significant. There are also no 0s after or inside the obvious significant figures. The significant figures are 4529.
