Est ce que qqn pourrais m’aider pour l’exercice 13 et 14 merci

bonsoir

a) 10 ³ * 10 ⁴ = 10 ⁷

b) 10 ² * 10 ⁻¹ = 10

c) ( 10²) ⁴ = 10 ⁸

d) 10 ³ : 10 ² = 10

e) 10 ³ : 10 ⁵ = 10 ⁻²

f) 10 ⁴ : 10 ⁻² = 10 ⁶

a = 10 ⁷ / 10 ² = 10 ⁵

b = 5 ⁷/ 5 ³ = 5 ⁴

c = 3 ⁶ / 3 ⁶ = 3 ⁰ = 1

d = 10 ⁵ / 10 ⁵ = 10 ⁰ = 1

Bonsoir

[tex]A = 10^{3} \times 10^{4}[/tex]

[tex]A = 10^{3+4} = 10^{7}[/tex]

[tex]B = 10^{2} \times {-1}[/tex]

[tex]B = 10^{2-1} = 10[/tex]

[tex]C = (10^{2})^{4}[/tex]

[tex]C = 10^{2\times4} = 10^{8}[/tex]

[tex]D = \dfrac{10^{3}}{10^{2}}[/tex]

[tex]D = 10^{3-2} = 10[/tex]

[tex]E = \dfrac{10^{3}}{10^{5}}[/tex]

[tex]E = 10^{3-5} = 10^{-2}[/tex]

[tex]F = \dfrac{10^{4}}{10^{-2}}[/tex]

[tex]F = 10^{4+2} = 10^{6}[/tex]

Exercice 14 :

A = [tex]\dfrac{10 \times 10^{5} \times 10}{10^{2}}[/tex]

[tex]A = 10^{1+5+1-2} = 10^{5}[/tex]

[tex] B = {5^{3} \times 5{4}}{5 \times 5^{2}}[/tex]

[tex]B = 5^{3+4-1-2} = 5^{4}[/tex]

[tex]C = \dfrac{3^{4} \times 3^{2}}{3 \times 3^{5}}[/tex]

[tex]C = 3^{4+2-1-5} = 3^{0} = 1[/tex]

[tex]D = \dfrac{10^{3} \times 10^{2}}{10 \times 10^{4}}[/tex]

[tex]D = 10^{3+2-1-4} = 10^{0} = 1[/tex]
