Using the correct number of significant figures, perform the following arithmetic: 539 x 7.2 =
The correct number of significant figures for this multiplication is two, as determined by the least number of significant figures in the given numbers.
539 x 7.2 = 3,884.8
However, since the second factor, 7.2, has two significant figures, the result must also have two significant figures. Therefore, the final answer is:
539 x 7.2 = 3,900
