5 0

The value of the given expression up to correct significant figures is 330 m^2.

  • The rule that applies 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 rule that applies for the addition and subtraction is :

The least precise number present after the decimal point determines the number of significant figures in the answer.

Given:

The expression: (23.4m)(14m)

To find:

The answer up to correct a number of significant figures.

Solution

Number of significant figures in '23.4' = 3

Number of significant figures in '14' = 22

=(23.4m)(14m)\\=(23.4m)\times (14m)\\=327.6 m^2

The number with the least significant figures is '14' is 2, so the answer will be reported up to 2 significant figures:

=327.6 m^2\approx 330 m^2

Number of significant figures in '330' = 3

The value of the given expression up to correct significant figures is 330 m^2.
