3.20. Амалдарды орындау:

1. $$ (4x^2)^3 = 4^3 cdot (x^2)^3 = 64x^6 $$

2. $$ (-2a^4b^2)^3 = (-2)^3 cdot (a^4)^3 cdot (b^2)^3 = -8a^{12}b^6 $$

3. $$ 0.3u^2 cdot (-\frac{1}{3}u^4v^6) = 0.3 cdot (-\frac{1}{3}) cdot u^2 cdot u^4 cdot v^6 = -0.1 u^6 v^6 $$

4. $$ (\frac{1}{4}x^2y)^3 cdot (-32x^2b) = (\frac{1}{4})^3 cdot (x^2)^3 cdot y^3 cdot (-32) cdot x^2 cdot b = \frac{1}{64} x^6 y^3 cdot (-32x^2b) = -\frac{32}{64} x^8 y^3 b = -\frac{1}{2} x^8 y^3 b $$
