When multiplying numbers with significant digits, count the total number of significant digits in each number. Multiply the numbers as usual, but round the final answer to match the least number of significant digits in the original numbers.
Significant digits in measurement refer to the digits in a number that carry meaning or contribute to the precision of the measurement. They indicate the level of accuracy or certainty in a measurement, with each significant digit representing a reliable and known value.
1. All non zero digits are significant numbers... e.g 12345, 12 ,3576 and all...! 2. All zeros between two non-zero digits are significant e.g 2007 and 9008...! 3. For numbers less than one zeros directly after the decimal point are not significant e.g 0.001 and 0.057..! 4. A zero to the right of the decimal place and following a non-zero digit is significant e.g 1.725...! 5. All other zeros at the left of a number are NOT considered as significant numbers e.g 0023...!
When adding numbers with significant figures, the result should be rounded to the least number of decimal places in the original numbers. Only the digits that are certain should be used in the final answer.
The frequency of a photon with a wavelength of 781 nm is approximately 384 THz (terahertz).
All the digits are significant in this case. A zero between other digits is always significant, and all zeros after the decimal point are significant.
Five. All nonzero digits are significant and zeros in between significant digits are significant.
Five. All nonzero digits are significant and zeros in between significant digits are always significant.
Five. All nonzero digits are significant and zeros in between significant digits are always significant.
Five. All nonzero digits are significant and zeros in between significant digits are always significant.
Four - zeros between significant digits are significant.
When multiplying numbers with significant digits, count the total number of significant digits in each number being multiplied. The result should have the same number of significant digits as the number with the fewest significant digits. Round the final answer to that number of significant digits.
to 1 significant digit: 8000 2 significant digits: 7700 3 significant digits: 7660 4 significant digits: 7656. 5 significant digits: 7656.0 6 significant digits: 7656.00 and so on and so forth for forever..........

It has 3 significant digits.
3 significant digits.
No, it has 3 significant digits.
