Explications étape par étape:

[tex]a = 10 {}^{3} \times 10 {}^{4} = 10 {}^{7} [/tex]

[tex]b = 10 {}^{ - 4} \times 10 {}^{6} = 10 {}^{2} [/tex]

[tex]c = 10 {}^{ - 3} \times 10 {}^{ - 4} = 10 {}^{ - 7} [/tex]

[tex]d = 10 \times 10 {}^{4} = 10 { }^{5} [/tex]

[tex]e = \frac{10 {}^{4} }{10 {}^{2} } = 10 { }^{2} [/tex]

[tex]f = \frac{10 {}^{4} }{10 {}^{ - 3} } = 10 {}^{7} [/tex]

[tex]g = \frac{10 {}^{ - 8} }{10 {}^{5} } = 10 {}^{ - 13} [/tex]
