a)
Interpretation : The answers in scientific notation are to be written.
Concept Introduction : A given number is stated as the product of two numbers in scientific notation: a coefficient and 10 raised to a power. Round the number to one significant figure in the measurement.
a)
Answer to Problem 7SP
The answer in scientific notation is
Explanation of Solution
The known digits plus the last, estimated digit make up the significant figures in a measurement.
There is a set of rules to detect the digits in a significant measured value.
Round the number to one significant figure in the measurement.
If the 2nd digit number is greater than or equal to 5, then the 1st digit is added up by number 1 while leaving the remaining digit after the 2nd digit. If the 2nd digit number is lesser than 5, then the values till the 1st digit are alone taken up.
The answer obtained is
The scientific notation is given as
