Explanation / Answer

5) 0479 x 0.7132 = 0.342 = 3.42*10^-1( three significant figures)

6) 830 -----------infinte nuber of significant figures because it may be written as 830.0 or 830.00 or 830.000--------

7) 7.69 ---------three significant figures -----7.69*10^0

8) 36.0 ----3.6*10^1-------three significant figures

note: in multiplication or division ,the final result should be report up to the same number of significant figures as are present in the term with least number of significant figures.

9) 1.3*10^2 -----two significant figures
