Significant figures are an indicator of the certainty in measurements

Significant figures communicate the level of precision in measurements

Answer 2

Explanation :

Significant figures : It is defined as the figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy (precision).

Significant figures in a measurement are all measured digits, and one estimated digit. That means, for example: 784 in this digit, the digit '78' are the certain digits but the digit '4' is an uncertain digit.

Hence, The correct options are,

Significant figures are an indicator of the certainty in measurements.

Significant figures communicate the level of precision in measurements.

Significant figures in a measurement are all measured digits, and one estimated digit.
