bonjour
2 ⁸ x 2 ⁻⁵ sur 2 ⁻¹⁰
= 2 ³ / 2 ⁻¹⁰
= 2 ¹³
( 2 ³)⁵ / 2 = 2 ¹⁵/2 ¹ = 2 ¹⁴
64/2⁹ = 2 ⁶ / 2 ⁹ = 2 ⁻³
1024 ¹⁰⁰ = ( 2 ¹⁰) ¹⁰⁰ = 2 ¹⁰⁰⁰
16 x 2 ⁹ = 2 ⁴ x 2 ⁹ = 2 ¹³
4 ⁵ / 2 ⁴ + 2 / 2 ⁻⁷ = ( 2 ²) ⁵ / 2 ⁴ + 2 / 2 ⁻⁷ = 2 ¹⁰ /2 ⁴ + 2 ⁸
= 2 ⁶ + 2 ⁸
81 x (1/3) ⁵ = 3 ⁴ x ( 3 ⁻¹) ⁵ = 3 ⁴ x 3 ⁻⁵ = 3 ⁻¹
27 ⁵ x 3 ⁶ / 9 ⁸ = ( 3³)⁵ x 3 ⁶ / ( 3²) ⁸ = 3 ¹⁵ x 3 ⁶ / 3 ¹⁶ = 3 ⁹/ 3 ¹⁶ = 3 ⁻⁷
