Salut :)

248.37 = 24.837 × 10 ¹ = 2.4837 × 10 ²
0.048 = 0.48 × 10 ⁻¹ = 4.8 × 10 ⁻² = 48 × 10 ⁻³
700000 =  700 × 10³ = 7 × 10⁵ = 0.07 × 10⁷
0.000003 =

Bonsoir

248,37 = 24,837 x  10  = 2,4837 x 10 ²

0.048 = 0.48 x 10 ⁻¹ = 4.8 x 10 ⁻² = 48 x 10⁻³

700 000 = 700 x 10³ = 7 x 10⁵ = 0,07 x 10 ⁷

0,000003 = 0,003 x 10⁻³ =3 x 10⁻⁶ = 300 x 10 ⁻⁹
