It might have been possible to answer the question if the "following" multiplication had followed. But since you did not bother to make sure that it did, I cannot provide a more useful answer.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
63
Significant figures are very important when it comes to calculations. If the mass of an electron is 9.10939 x 10-31 then its significant figures are: 9 x 10^-31( correct 1 significant figure), 9.1 x 10^-31 kg ( correct to 2 significant figures), 9.11 x 10^-31 (correct to 3 significant figures), and 9.109 x 10^-31 (correct to 4 significant figures).
The correct answer is 2. The three zeros between the decimal point and the 1 are place holders but they are NOT significant digits. See, for example, the Wikipedia link.
There are 4 significant figures in 0.0032. Seems to be only 2 significant figures in this number.
103.9302.3
It has three significant figures.
63.6615
192
78.24 since you had two decimal places in the multiplier you'll have two in the answer.
There should be 3.
6 of them.
The answer depends on what operations were used. There should normally not be more significant figures in the answer than in any of the numbers used in the calculation.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
7.34
4 significant figures.
which is the correct product of the significant figures 3.278 and 4.23.
4,566 to 3 significant figures is 4,570.
10 significant figures.
