How would you record a measurement of 16490 grams using only 2 significant figures?
The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". When 16490 is rounded off to 2 significant figures then the first figure to be discarded is 4. As this is less than 5 then the previous figure (6) is not increased by 1. 16490 to 2 significant figures is 16000.

How do you express 480 in exponential notation only using one significant figure?
We need to first move the decimal two (2) places to the left: 480 = 4.80 x 102 The 2 in 102 comes from how many places we moved the decimal. It's positive because the number it represents is larger (480 > 4.8) With one significant figure, we need to round to the nearest whole number: 5 x 102 The answer is 5 x 102
