Question

Which is most accurate?
(A)$3m$
(B)$3.0m$
(C)$3.00m$
(D)$3.000m$

Answer 1

Zeros to one side of the last non-zero digit (following zeros) in a number with the decimal point are critical in case they are inside the estimation or announcing goal. Critical figures of a number in positional documentation are digits in the number that are solid.
The puts on the left side or entire number part start with ones, trailed by tens, then, at that point, hundreds, trailed by thousands, etc. The puts on the right or fragmentary part start with tenths, trailed by hundredths, then, at that point thousandths, etc.

Complete answer:
The more exact the estimating device, the more exact precise the estimations can be.
Critical figures show the accuracy of an estimating device that was utilized to gauge a worth.

This is valid regardless of whether the digit is zero, etc.
We cycle a number to three critical figures similarly that we would adjust to three decimal spots. We count from the primary non-zero digit for three digits.
The quantity of critical figures utilized suggests a specific most extreme blunder range.

So, the correct answer is “option D”.

Note:
Significant figures are any non-zero digits or caught zeros. They do exclude driving or following zeros. The last reply in an increase or division issue ought to contain a similar number of huge figures as the first number with the least critical figures. The Model Builder is a decent alternative and once in a while the main choice when attempting to accomplish a more confounded design. I will now and then add a logging proclamation (for the improvement climate) in a task that likewise utilizes information comments since it has a possibility of being seen by a designer if startling conduct is being noticed.
