Question

3,81 x 10 (elevado a -2) - 4,23 x 10 (elevado a -3) =

Answer 1

Resposta:

$3,81 * 10^{-2} - 4,23 * 10^{-3} =\\\\3,81 * (\frac{10}{1}) ^{-2} - 4,23 * (\frac{10}{1}) ^{-3} =\\\\3,81 * (\frac{1}{10}) ^{2} - 4,23 *( \frac{1}{10}) ^{3} =\\\\3,81 * 0,1^{2} - 4,23 * 0,1^{3} =\\\\3,81 * 0,01 - 4,23 * 0,001 =\\\\0,0381 - 0,00432 = \\\\0,03387$
