Multiplication and division When multiplying or dividing, the final answer is rounded to the same number of significant figures as the measured number with the fewest significant figures. Addition and subtraction When adding or subtracting, the final answer is rounded to the same number of digits to the right of the decimal point as the measured number with the fewest digits to the right of the decimal point.   Part A Compute 2.345 × 4.48697. Round the answer appropriately. Express your answer numerically using the proper number of significant figures.   Part B Compute 1240.64 / 64. Round the answer appropriately. Express your answer numerically using the proper number of significant figures.   Part C Compute 21405.6 + 9.3456 . Round the answer appropriately. Express your answer numerically using the proper number of significant figures.

Complete the following operations and write your answer with the correct number of significant figures. Use scientific notation when appropriate. (7.87 x 10-5)(1.84 x 10-2) =

What answer should be reported, with the correct number of significant figures, for the following calculation? (965.43 x 3.911) + 9413.4136 13189 13189.2 1.319 x 104 O 1.3 x 104 1.32 x 104 1 nts

Put in Scientific notation  1.(5.86x10^6)(1.00x10^-8)= 2. (8.90x10^-5)(7.49x10^-4)/ (1.00x10^-8)(1.57x10^-4)=

What answer should be reported, with the correct number of significant figures, for the following calculation? (965.43 × 3.911) + 9413.4136 13189 1.319 x 104 1.3 x 104 1.32 x 104 13189.2

Calculate and give the correct number of significant figures: (4.5 × 10-14) × (5.2 × 103) = (6.1 × 105) / (1.2 × 10-3) = (3.74 × 10-3)4 =

Use the References to access important values if needed for this question. It is often necessary to do calculations using scientific notation when working chemistry problems. For practice, perform each of the following calculations. (7.46 × 10°) (1.00 × 10-8) = 2.58 × 104 3.90 × 104 = 7.46 × 106) (3.90 × X 104) (7.11 × 105) (9.70 × 10-4) x
