Question 3 Give the answer to the correct number of significant figures: 4.596 - 2.81 =? Question 4 Give the answer to the correct number of significant figures: (4.58 x 10) x (4.3198 x 10-19) =? Question 5 Give the answer in scientific notation and to the correct number of significant figures: (7860) / (0.00001)=?arrow_forward» Significant Figure Rules 01 >> 02 >> 03 >> 04 >> 05 >> All nonzero digits are significant. Zeros that appear between other nonzero digits are always significant. Zeros that appear in front of all of the nonzero digits are called left-end zeros. Left-end zeros are never significant. Zeros that appear after all nonzero digits are called right-end zeros. Right-end zeros in a number that locks a decimal point are not significant. ▬▬▬ 美銀銀時 ☐☐ Right-end zeros in a number with a decimal point are significant. This is true whether the zeros occur before or ofter the decimal point. 237 has three significant figures. 1.897 has four significant figures. 39,004 has five significant figures. 5.02 has three significant figures. 0.008 has one significant figure. 0.000416 has three significant figures. 140 has two significant figures. 75,210 has four significant figures. 620.0 has four significant figures. 19.000 has five significant figures. For multiplication and division problems, the answer…arrow_forward

- 26. What is the number of significant figures does the sum of the following contain 3.+5.652, the answer is 0.3+5.652 , the answer isarrow_forwardExpress the answer to the following calculations in proper number of significant figures.arrow_forwardbetween significant digits are always significant. figures. Example: 5,007 has 4 significant figures. 3) Trailing zeros in a number are significant only If the number contalns a decimal polnt. Example: 100.0 has 4 significant figures. 100 has 1 significant figure. 4) Zeros in the beginning of a number whose only function Is to place the decimal polnt are not significant. Example: 0.0025 has 2 significant figures. 5) Zeros following a decimal significant figure are significant. Example: 0.000470 has 3 significant figures. 0.47000 has 5 signlficant figures.
