 The exercises below use the following notation: ^ means to the power of ¬ will be used to mean square root / means divide * means multiply Hope it's not too confusing, I recommend writing the questions out if it is. Exercise 1A 1. 4^(1/2)    2. 16^(1/2)   3. 8^(1/3)    4. 243^(1/5) 5. 243^(3/5)  6. 8^(-2/3)   7. 10^0       8. 10^(-2) 9. (-7)^-3)   10. (6and1/4)^(1/2)    11. (1and7/9)^(1/2) 12. (4/9)^(-1/2)  13. (8/27)^(2/3)   14. (-27)^(2/3) 15. (5/6)^0     16. (5/6)^(-1)       17. (5/6)^(-2) 18. (15and5/8)^(2/3)   19. (16/25)^(-1/2) 20. (2and7/81)^(1/2)   21. 125^(-2/3) 22. 1296^(1/4)         23.
