Studdy Solution
STEP 1
Assumptions1. We are asked to find the number of significant figures in the number . . The rules for significant figures are as follows a. Any non-zero digit is a significant figure. b. Any zeros between significant figures are significant. c. Leading zeros are not significant. d. Trailing zeros are significant if they are after a decimal point.
STEP 2
Identify the non-zero digits in the number. These are all significant.
In , the non-zero digits are7 and5.
STEP 3
Identify any zeros between significant figures. These are also significant.
In , there are no zeros between significant figures.
STEP 4
Identify any leading zeros. These are not significant.
In , there are no leading zeros.
STEP 5
Identify any trailing zeros. These are significant if they are after a decimal point.
In , there are three trailing zeros after the decimal point.
STEP 6
Add up the number of significant figures from steps2,3 and5.
The total number of significant figures in is .
So, there are5 significant figures in .
