It is always the last digit.
There need no be any estimated digit.
To estimate the digit in 4500 miles, you can round it to the nearest thousand, which would be 5000 miles. The most significant digit in this estimate is 5. Therefore, when considering the estimated digit, it would be 5.
The estimated digit in 42.50 g is the last digit, which is 0. The value is expressed to two decimal places, indicating that the measurement is precise to the hundredths place. Thus, the estimated digit reflects a level of uncertainty in the measurement, suggesting it could range from 42.495 g to 42.505 g.
The last one.
The 7
There need no be any estimated digit.
The last digit is always the estimated digit in a number
There need not be any estimated digit but, if there must be one, then it is the last digit: 3.
500
There need not be any estimated digit: there could well be exactly 4500.
Oh, dude, you're hitting me with the math questions now? Like, chill, I got this. The estimated digit in 0.0782m is 8 because it's the third digit after the decimal point. But hey, who's counting, right?
.0002 is the estimated number
To estimate the digit in 4500 miles, you can round it to the nearest thousand, which would be 5000 miles. The most significant digit in this estimate is 5. Therefore, when considering the estimated digit, it would be 5.
It is 0.08 M
It is the zero at the end.
The estimated digit in 42.50 g is the last digit, which is 0. The value is expressed to two decimal places, indicating that the measurement is precise to the hundredths place. Thus, the estimated digit reflects a level of uncertainty in the measurement, suggesting it could range from 42.495 g to 42.505 g.
None of the digits need be estimated.
