1. 0,02a * 10b * 30 = 0,2ab * 30 = 6ab

2. 2*3³-4² = 2*27-16 = 54-16 = 38

3. -6ab² * -3a³b = 18a⁴b³

4. (-1/4 x²y⁶)² = 1/16 x⁴y¹²

5. a¹²:a⁴*a⁷ = a¹⁵

6. (-3ab²c³)² = 9a²b⁴c⁶

7. a) 3¹⁰*27²/81⁴ = 3¹⁰*3⁶/3¹⁶ = 3⁶/3⁶ = 1

b) 18⁷/8²*81³ = 18⁷/64*81³ = 18

8. (-1/2x⁴y)⁴ * (16x⁴y³)² = 16x²⁴y¹⁰

9. (-2ab³) * (-3a²b⁴)
