Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the multiplication and division is :
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
The given expression is:
[tex](4.62)\times (4.48697)[/tex]
[tex]\Rightarrow 20.7298014[/tex]
[tex]\Rightarrow 20.7[/tex]
In the given expression, 4.62 has 3 significant figures, 4.48697 has 6 significant figures. From this we conclude that 3 is the least significant figures in this problem. So, the answer should be in 3 significant figures.
