3² = 9
- 2 ³ = - 8
( - 4 )² = 16
5 ⁰ = 1
4 + 3 * 2 ³ = 4 + 3 *8 = 4 + 24 = 28
- 4 ² - 3 ³ = - 16 - 27 = - 43

10 ⁻³ = 0.001
10⁶ = 1 000 000
1/10 ⁻⁵ = 100 000
1 /10² = 1/100 = 0.01
***************************************************************************
10 ⁷ * 10 ³ = 10 ¹⁰
10 ⁻¹⁰ / 10 ⁻⁴ = 10 ⁻⁶
10⁸ * 10 ⁻⁵ = 10 ³
( 10 ⁻⁸) ⁴ = 10 ⁻³²
10⁶/10² = 10 ⁴
( 10 ⁶) ² = 10 ¹²

3 794 = 3.794 * 10 ³
6.13 * 10⁶ est une écriture scientifique
- 0.005 6 = 5.6 * 10 ⁻³
0.073 * 10 ⁻⁴ = 7.3 * 10 ⁻⁶
