| 1. | x1 = x |
| 2. | x0 = 1 |
| 3. | X -n = 1/xn |
| 4. | (xm)(xn) = xm+n |
| 5. | xm / xn = xm-n = 1/(x n-m) |
| 6. | (xm)(ym) = (xy)m |
| 7. | (xm)n = xmn |
| 8. | (xy)n = xnyn |
| 9. | (x/y)m = xm/ym |
| 10. | xm = xn then m = n |
Keep in Mind
· xmyn ≠ (xy)m+n |
· (xm) n ≠ xm x n |
· (x+y) m ≠ xm + y m |
· √(x2 + y2 ) ≠ x+y |
· (-y) 2 ≠ – y2 |
· m/(x + y ) ≠ m/x + m/y |
