Accepted Answer

Vamos resolver os exercícios um por um:

**b.** $\frac{7 \times 10^2}{0,3 \times 10^{-4}} = \frac{7}{0,3} \times 10^{2 - (-4)} = \frac{7}{0,3} \times 10^{6} = 23,33 \times 10^{6} = 2,333 \times 10^7$

**c.** $\frac{0,55 \times 10^9}{3 \times 10^{-6}} = \frac{0,55}{3} \times 10^{9 - (-6)} = 0,1833 \times 10^{15} = 1,833 \times 10^{14}$

**d.** $\frac{17 \times 10^3}{0,3 \times 10^{-3}} = \frac{17}{0,3} \times 10^{3 - (-3)} = 56,67 \times 10^{6} = 5,667 \times 10^7$

**e.** $\frac{17 \times 10^{-5}}{9,2 \times 10^{-4}} = \frac{17}{9,2} \times 10^{-5 - (-4)} = 1,8478 \times 10^{-1} = 1,8478 \times 10^{-1}$

**f.** $1,2 \times 10^{12} \times 79,1 \times 10^2 = (1,2 \times 79,1) \times 10^{12+2} = 94,92 \times 10^{14} = 9,492 \times 10^{15}$

**g.** $2 \times 10^3 \times 9,7 \times 10^2 = (2 \times 9,7) \times 10^{3+2} = 19,4 \times 10^{5} = 1,94 \times 10^{6}$

**h.** $91,3 \times 10^9 \times 8,1 \times 10^4 = (91,3 \times 8,1) \times 10^{9+4} = 739,53 \times 10^{13} = 7,3953 \times 10^{15}$

**i.** $2,1 \times 10^3 + 9,1 \times 10^3 = (2,1 + 9,1) \times 10^3 = 11,2 \times 10^3 = 1,12 \times 10^4$

**j.** $2,9 \times 10^8 - 1,3 \times 10^8 = (2,9 - 1,3) \times 10^8 = 1,6 \times 10^8$
