PROBLEM
Find the number of significant digits in the measurement .
STEP 1
Assumptions1. The measurement is
STEP 2
To determine the number of significant digits in a measurement, we need to understand the rules of significant figures.1. Non-zero digits are always significant.
2. Any zeros between significant digits are significant.
. Leading zeros are not significant.
4. Trailing zeros are significant only if the number contains a decimal point.
STEP 3
Now, let's apply these rules to our measurement .
STEP 4
The number has four digits , , , and .
STEP 5
According to the rules, all non-zero digits are significant. So, and are significant.
STEP 6
The zero between $$ and $0$ is also significant because it is between significant digits.
STEP 7
The zero after the decimal point is significant because it is between significant digits.
SOLUTION
So, all four digits in are significant.
Therefore, the number of significant digits in the measurement is4.
