1. b² x b ⁵ = b ⁷
2. 1000 000 = 10 ⁶
3. x² * x ⁷ = x ⁹
4. ( a x b ) ⁷ = a ⁷ x b ⁷
5. ( 10 ² ) ⁴ = 10 ⁸
6. a * a ⁿ * a ² = a ⁿ ⁺³
7. 7 ⁰ = 1
8. [ ( 3/5)²] ⁴ = ( 3/5 ) ⁸
9. 4 = 2² ; 8 = 2 ³ ; 16 = 2 ⁴
25 = 5 ² ; 27 = 3 ³ ; 81 = 3⁴
10. 2 ³ x 8 = 2 ³ x 2 ³ = 2 ⁶
5² x 5 ³ = 5 ⁵
9 ² x 3 ³ = ( 3 ²)² x 3 ³ = 3 ⁴ x 3 ³ = 3 ⁷
