1,27 × 10^-3 и 5,41 × 10^-4

Answer 1

$1.27 \times 10{}^{ - 3} = \frac{127}{100} \times \frac{1}{ {10}^{3} } = \frac{127}{100 \times {10}^{3} } = \frac{127}{100 \times 1000} = \frac{127}{100000} = 0.00127 \\ \\ 5.41 \times {10}^{ - 4} = \frac{541}{100} \times \frac{1}{ {10}^{4} } = \frac{541}{100 \times {10}^{4} } = \frac{541}{100 \times 10000} = \frac{541}{1000000} = 0.000541 \\ \\ - - - - - - - - - - - - - - - - - \\ 0.00127 > 0.000541$
