Question

scrieti cu ajutorul puterilor lui 10(pozitive sau negative ) numerele: 0,021; 0,1; 1,02 si 1000

Answer 1

 0,021=21/1000=21 *10⁻³
 0,1=1/10 =10⁻¹
 1,02 =102/100=102 *10⁻²
 1000=10³

Answer 2

$0,021=21 \frac{1}{ 10^{3} }$=21ori$10^{-3}$
$0,1=\frac{1}{10}$
$1,02= \frac{102}{100} =102ori10^{-2}$
$1000= 10^{3}$
