Bonjour,

[tex]G = \frac{(10 {}^{3} ) {}^{5} \times 10 {}^{ - 4} }{10 {}^{2} \times 10 {}^{7} } = \frac{10 {}^{15} \times 10 {}^{ - 4} }{10 {}^{2} \times {10}^{7} } = \frac{10 {}^{15 - 4} }{10 {}^{2 + 7} } = \frac{10 {}^{11} }{10 {}^{9} } = 10 {}^{11 - 9} = 10 {}^{2} [/tex]

→ On en déduit que l'exposant est 2
