Answer
4.85
Explanation
3.60×102 significant figure is 3
1.70×10-3 significacant figure is 3
2.196×10-3 significant figure is 4
57.5 significant figure is 3
lowest significant figure is 3, so answer should be with 3 significant figure.
(3.60×102)(1.70×10-3)/((2.196×10-3) (57.5)) = 0.0485×102 = 4.85
