Donnell is allergic to pollen. The Diameter of a grain of pollen is between 1.2 x 10 to the negative^5m. and 9 x 10 to the negative^5m. Donnells air conditioner has a filter that removes particles larger than 3 x 10 to the negative^7m. Will the filter remove pollen? Explain.

Diameter is between:
.000012m and .00009 m
His filter removes things that are .0000003 m
.0000003 < .00009
.0000003 < .000012
So therefore itll remove pollen perfectly

Yes it remove the pollen because when you write the numbers out 1.2*10^-5 and 9*10^-5 ends up with four zeros and 3*10^-7 ends up with 6 zeros. The number with the greatest number of zeros is the bigger number. Since 3*10^7 is the smaller than the other two it can remove the pollen.
