Question

Запиши число a в стандартном виде:

a=3,51⋅10^−6/3⋅10^−3




​

Answer 1

$a = 3.51 \times 10 {}^{ - \frac{6}{3} } \times 10 {}^{ - 3} \\ a = 3.51 \times 10 {}^{ - 2} \times 10 {}^{ - 3} \\ a = 3.51 \times 10 {}^{ - 5} \\ a = \frac{351}{100} \times \frac{1}{10 {}^{5} } \\ a = \frac{351}{100 \times 10 {}^{5} } \\ a = \frac{351}{10 {}^{2} \times 10 {}^{5} } \\ a = \frac{351}{10 {}^{7} }$
