Answer

Voici les valeurs classées dans l'ordre croissant : 1. \( 45,5 \times 10^{-11} \) 2. \( 14000 \times 10^{1} \) 3. \( 27,9 \times 10^{9} \) 4. \( 245000 \times 10^{8} \)

Solution

Calculons les valeurs de chaque expression donnée : a. \( 4,5 \times 10^{7} \times 6,2 \times 10^{2} \) \( 4,5 \times 10^{7} \times 6,2 \times 10^{2} = 4,5 \times 6,2 \times 10^{7+2} = 27,9 \times 10^{9} \) b. \( 700 \times 10^{6} \times 350 \times 10^{2} \) \( 700 \times 10^{6} \times 350 \times 10^{2} = 700 \times 350 \times 10^{6+2} = 245000 \times 10^{8} \) c. \( 280 \times 10^{5} \times 50 \times 10^{-4} \) \( 280 \times 10^{5} \times 50 \times 10^{-4} = 280 \times 50 \times 10^{5-4} = 14000 \times 10^{1} \) d. \( 65 \times 10^{-5} \times 0,7 \times 10^{-6} \) \( 65 \times 10^{-5} \times 0,7 \times 10^{-6} = 65 \times 0,7 \times 10^{-5-6} = 45,5 \times 10^{-11} \) Maintenant, classons les valeurs dans l'ordre croissant : 1. \( 45,5 \times 10^{-11} \) 2. \( 14000 \times 10^{1} \) 3. \( 27,9 \times 10^{9} \) 4. \( 245000 \times 10^{8} \)

Beyond the Answer

Pour traiter ces expressions, on commence par les simplifier en multipliant les coefficients et en ajoutant les puissances de 10. a. \( 4,5 \times 10^{7} \times 6,2 \times 10^{2} = 27,9 \times 10^{9} = 2,79 \times 10^{10} \) b. \( 700 \times 10^{6} \times 350 \times 10^{2} = 245000 \times 10^{8} = 2,45 \times 10^{13} \) c. \( 280 \times 10^{5} \times 50 \times 10^{-4} = 14000 \times 10^{1} = 1,4 \times 10^{5} \) d. \( 65 \times 10^{-5} \times 0,7 \times 10^{-6} = 45,5 \times 10^{-11} = 4,55 \times 10^{-10} \) En les classant dans l’ordre croissant, on obtient : d. \( 4,55 \times 10^{-10} \) c. \( 1,4 \times 10^{5} \) a. \( 2,79 \times 10^{10} \) b. \( 2,45 \times 10^{13} \)
