Answer:
The answer is 2
Explanation:
First you solve each part in the numerator:
- ( 29.2 - 20.0 ) = 9.2
- (1.79 x 10^5) = 179,000
now multiply these: 179,000 x 9.2 = 1646800
Divide: 1646800 ÷ 1.39 = 1184748.201
In these, you can see that the result of the first equation has the least amount of significant figures. When determining how many SigFigs are in a given computation, your answer will be the number of SigFigs in the number with the least SigFigs.
Even if you divide 1646800 by 1.39, 9.2 is still the number with the least amount of significant figures in all the computations and terms given.
