Correct each of the following errors by circling the error, describing what is wrong, entering what should be there instead, and entering the correct answer. 1. (3x2)(-2x4) = 3(-2)x2•4 = 6x8 2. 4a2 • 3a5 = (4 + 3)a2 + 5 = 7a7 3. x6 • x • x3 = x6+3 = x9 4. 34 • 23 = 64+3 Using the properties you've learned, complete each equation and solve for the variable. 5. 82 • 8x = 811 6. 57 • 5b = 53 7. x12 • xn = x12 Simplify. 8. (2x2y3)(4xy-2) 9. -4x3(2x2 - 9x) 10. 4y+1 • 41-x 11. 5t-2 • 2t-5 12. (3x)4 13. (6m4)2 14. (x2)5(x3)2 15. (3b-2)2(a2b4)3 16. (2a2b5)-4(b-1a8)6 Simplify. 17. 18. 19. 20. 21. 22.
