1 . 1 / 3 ⁻² = 3 ²

2. 10 ² x 25 ⁻³ x 20 ⁴ = ( 2 x 5 )² x ( 5 ²) ⁻³ x ( 2 ² x 5 )⁴

= 2 ² x 5 ² x5 ⁻⁶ x 2 ⁸ x 5 ⁴

= 2 ¹⁰ x 5 ⁰ = 2 ¹⁰ x 1 = 2 ¹⁰

3. (3 ⁹ x 3) : (3 ⁵ x 3 ² ) = 3 ¹⁰ / 3 ⁷ = 3 ³

4. ( 6 ² ) ³ x 6 ⁵ sur 6 ⁻¹ x 6 ³ x 6 ³

= 6 ⁶ x 6 ⁵ sur 6 ⁵

= 6 ¹¹ / 6 ⁵ = 6 ⁶

4 √96 - 4 √24 - 4 √54

= 4 √16 * √6 - 4 √ 6 * √4 - 4 √ 6 * √ 9

= 16 √6 - 8 √6 - 12 √6

= - 4 √6

2 √63 x √112 = 2 √7 *√9 x √16 * √7

= 6 √7 x 4 √7

= 24 * 7 = 168

24 √18 / 9 √32

= 24 √18 ( 9 √32 ) : ( 9 √32 )²

= 216 √ 576 ; 2 592

= 5 184 : 2 592

= 2

( √3 - 1 ) ( 3 + √3)

= 3 √3 + 3 - 3 - √3

= 2 √3
