1. 2⁶x2³ = 2^6+3 = 2⁹ = 512
2. 8⁵x(-8)⁴ = 8^5+4 = 8⁹ = 134.217.728
3. 3^-4x3^-5 = 3 ^-4+(-5) = 3^-9 = -19. 683
4. 8^-3:8^-1 = 8^-3-(-1) = 8^-2 = 1/8² = 1/64
5. 10^-5:5^-3 = 1/10⁵:1/5³ = 1/10⁵×5³/1 = 5³/10⁵ = 5³/(2×5)⁵ = 5³/2⁵×5⁵ = 1/2⁵×5^5-3 = 1/2⁵x5² = 1/32x25 = 1/800
6. 12^-2:4^-2 = 1/12²:1/4² = 1/12²×4²/1 = 4²/12² = 16/144 = 1/9
7. 2^-5×5^-5 = 1/2⁵×1/5⁵ =1/2⁵×5⁵ = 1/32×3125 = 1/100.000
8. 4^-3×5^-3 = 1/4³×1/5³ = 1/4³×5³ = 1/64×125 = 1/8.000
9. 5^-4×2^-6 = 1/5⁴×1/2⁶ = 1/5⁴×2⁶ = 1/625×64 = 1/40.000
10. 2^-3×4^-2 = 1/2³×1/4² = 1/2³×4² = 1/8×16 = 128
