Answer 1

Resposta:

73/10000

Explicação passo-a-passo:

$2.1.10. {}^{ - 3} + 5.2.10 {}^{ - 3} = \\ 2.1.10 {}^{ - 3} + 5.2.10 {}^{ - 3} \\ 2 \times1 \times 10 {}^{ - 3} + 5 \times 2 \times 10 {}^{ - 3} \\ (2.1 + 5.2) \times 10 {}^{ - 3} \\7.3 \times 10 {}^{ - 3} \\ 2.1 \times 10 {}^{ - 3} + 5.2 \times 10 {}^{ - 3} \\ 7.3 \times 10 {}^{ - 3} \\ \frac{73}{10} \times 10 {}^{ - 3} \\ 7.3 \times 10 {}^{ - 3} \\ \frac{73}{10} \times \frac{1}{10 {}^{ - 3} } \\ \frac{73 \times 1}{10 \times 10 {}^{3} } \\ \frac{73}{10 \times 10 {}^{3} } \\ \frac{73 \times 1}{10 \times 10 {}^{3} } \\ \frac{73}{10 {}^{1 } \times 10 {}^{3} } \\ \frac{73}{10 {}^{1 + 3} } \\ \frac{73}{10 {}^{4}} \\ \frac{73}{10} \times \frac{1}{10 {}^{3} } \\ \frac{73}{10 {}^{4} } \\ {10}^{4} \\ 10 \times 10 \times 10 \times 10 \\ 10000 \\ \frac{73}{10 {}^{4} } \\ \frac{73}{10000} \\ resposta \\ \frac{73}{10000}$
