1).a. 7.200 : 3 = 2.400 = 2,4 x 10³b. 4 x 7 x [tex]10^{-6}[/tex] = 28 x [tex]10^{-6}[/tex] = 2,8 x [tex]10^{-5}[/tex]c. 0,5 x 10⁴ x [tex]10^{-6}[/tex] = 0,5 x [tex]10^{-2}[/tex] = 5 x [tex]10^{-3}[/tex]d. 130 x 6.000 = 780.000 = 7,8 x [tex]10^{5}[/tex]2).a. 3,8 x 10³ = 3.800b. 2,43 x [tex]10^{5}[/tex] = 243.000c. 5,12 x [tex]10^{-2}[/tex] = 0,0512d. 6,2 x [tex]10^{-4}[/tex] = 0,000623). a. [tex](0,003)^4 \cdot (0,0005)^2 \\ = (3 \times 10^{-3})^4 \cdot (5 \times 10^{-4})^2 \\ = 81 \times 10^{-12} \cdot 25 \times 10^{-8} \\ = 2025 \times 10^{-20} \\ = 2,025 \times 10^{-17}[/tex]b. [tex]\frac{(0,0004)^3 \cdot (0,0002)^{-3}}{(0,0005)^2} \\ = \frac{(4 \times 10^{-4})^3 \cdot (2 \times 10^{-4})^{-3}}{(5 \times 10^{-4})^2} \\ = \frac{64 \times 10^{-12} \cdot \frac{1}{8} \times 10^{12}}{25 \times 10^{-8}} \\ = \frac{8}{25} \times 10^8 \\ = 0,32 \times 10^8 \\ = 3,2 \times 10^7[/tex]4). 30.224.050 = 30.220.000 = 3,0224050 x [tex]10^{7}[/tex] = 3,02 x [tex]10^{7}[/tex]5). 8 x 0,0006 = 0,0048 = 4,8 x [tex]10^{-3}[/tex]
