a) -3ab(6a^{2} - 2ab - b^{2}) - (3ab^{3} + 6a^{2}b^{2})

b) 6a(5a^{2} - 8b) - 10a(6b+7a^{2}) - 3ab

c) [(8x^{3} - 4 x^{2}y^{2}) - 2 (3x^{2}y^{2} + 4x^{3})] *(-2x^{2}y^{2}

d) 4c - 2(c-3)- 3 [c-3(4-2c)+8]

2.Wykonaj działania.

a) 3a\sqrt{2}(\frac{2}{3} \sqrt{32} - \frac{1}{3}\sqrt{6} +2 \sqrt{8})

b)(2a\sqrt{12} + \frac{a}{3} \sqrt{27} - \sqrt{3}) * \sqrt{3}

c)\sqrt{\frac{1}{3}} (2x\sqrt{6} + 4 \sqrt{3} - 3\sqrt{\frac{1}{3}} + x\sqrt{54})

Z góry dziękuję. ;*
