bonjour
A =3 ³ ( 23 - 5 ²) ³ + ( 2 - 3 ) ⁴
= 27 ( - 2) ³ + ( - 1 ) ⁴
= 27 * - 8 - 1
= - 216 - 1
= - 217
B = 2 ( 8 - 3 )² + 3 * 2 ³
= 2 * 5² + 3 * 8
= 50 + 24
= 74
A = 3 ⁴ * ( 3 ⁻²) ⁶ * 3 ⁵
= 3 ⁴ * 3 ⁻¹² * 3 ⁵
= 3 ⁻³
B = 3 ⁷ / 3 ⁸ * 3 ⁻⁵
= 3 ⁷/ 3 ³
= 3 ⁴
C = [( 3⁴/ 3 ¹¹ * 3 )]²
= ( 3⁴/ 3¹²)²
= ( 3 ⁻⁸ )²
= 3 ⁻¹⁶
D = 27 * 9 ⁵
= 3 ³ * ( 3²) ⁵
= 3 ³ * 3 ¹⁰
= 3 ¹³
E = 81 ⁴ * 9 ⁻² / 27 ⁻³
= ( 3⁴)⁴ * ( 3²) ⁻² / ( 3 ³)⁻³
= 3 ¹⁶ * 3 ⁻⁴ / 3 ⁻⁹
= 3 ¹² / 3 ⁻⁹
= 3 ²¹
F = 9 ⁻³ * 81 ²
= ( 3²) ⁻³ * (3 ⁴)²
= 3 ⁻⁶ * 3 ⁸
= 3 ²
A = 5.3 * 10 ⁹
B = 4.723 * 10 ⁻⁸
C = 24.4808 * 10 ⁷ = 2.44808000 * 10 ⁸
D = 5.125 * 10 ⁻⁴ / 2.3 * 10 ⁻⁷
= 2.22826087 * 10 ³
