When multiplying, the number of significant numbers in the answer should be the same as the fewest significant figures in the problem. Both 13.5 and 3.00 have three significant figures, so the answer will have three significant figures. 13.5 x 3.00 = 40.5 exactly (no need to round).
To determine which number has exactly three significant figures, you would need to evaluate the options provided. Significant figures include all non-zero digits, any zeros between significant digits, and trailing zeros in a decimal number. For example, 0.0456 has three significant figures, while 0.00456 only has three significant figures if we consider the non-zero digits and the zero between them. Please provide the specific numbers to evaluate.
It is then 2.64 when rounded to three significant figures
3 significant figures
There are 4 of them
That depends on how many significant figures you are talking about.If three significant figures then 700 is the largest that rounds to 700.If four significant figures are to be rounded to three significant figures then 700.4If five significant figures are to be rounded to three significant figures then 700.49If six significant figures are to be rounded to three significant figures then 700.499etc.
