bonjour
a = 6 ⁹ / 6 ⁵ = 6 ⁴
b = 11 ² / 11 ² = 11 ⁰ = 1
c = 5 ⁶/ 2² = 5 ⁴
a = 12 ²
b = 25 x 0.2 ² = 5² x 0.2 ² = 1 ² = 1
c = ( 3²) ⁵ / 3 ⁶ = 3 ¹⁰ / 3 ⁶ = 3 ⁴
a . 5 ⁴ x 5 ³ = 5 ⁷
b 2 ³ x 2 ⁵ = 2 ⁸
c 3 ⁵ x 3 ² = 3 ⁷
a . ( 3 ³)² x 3 ⁴ = 3 ⁶ x 3 ⁴ = 3 ¹⁰
b . ( 3 ³)² x (3²)² = 3 ⁶ x 3 ⁴ = 3 ¹⁰
c. 4² x 0.25 ² = 1 ² = 1
