Question
For each of these problems, complete the answer with a 10 raised to the proper power. Note that each answer is expressed to the correct number of significant figures. (a) 2.71 times 10^4 times 2.0 times 10^2 = (a) _____ (b) 4.523 times 10^4/2.71 times 10^2 = (b) _____ (c) 4.8 times 10^4 times 3.5 times 10^4 = (c) _____ (d) 4.523 times 10^-4/1.2 times 10^2 = (d) _____ (e) 4.70 times 10^2/8.42 times 10^5 = (e) ______ Solve each of the following problems, expressing each answer to the proper number of significant figure. Use exponential notation for (c), (d), and (e) (a) 1.842 + 45.2 + 87.55 (a) _____ (b) 714.3 - 28.525 (b) ______ (c) 2.83 times 10^4 times 7.55 times 10^7 = (c) _______ (d) 3.3 times 5280 = (d) _______ (e) 7.07 times 10^-4 times 6.51 times 10^-2/2.92 times 10^4 = (e) _____ (f) 8714.3 - 28 (f) ______Explanation / Answer
a) 271 * 102 * 2.0 * 102 = 54200000 = 3 significant figure
b) 166.900 = 167= 3 significant figure
c) 168000000= 3 significant figure
d) - 0.15 = -0.2 = 1 significant figure
