Question

$0.6x^{4} (-10x^{4} )^{3}$
$0.6x^{2} y (-0.5x^{5} y^{7})$
$(2a^{7} x^{12} )^{4} \frac{1}{8} ax$
$3a^{3} 3 (2a^{2} - 4)$
$(3a^{2}-11a+4)-(6a^{2} -2a-3)$

Answer 1

Ответ:

1)-0.6х¹⁶

2)-0.3х⁷у⁸

3)0.25а²⁹х⁴⁹

4)18а⁵-36а³

5)18а⁴+72а3-17а²-41а-12

Объяснение:

1)0.6х⁴(-10х⁴)³=0.6*-10х⁴+⁴*³=-0.6х¹⁶

2)0.6х²у(-0.5х⁶у⁷)=0.6*-0.5х²+⁶у¹+⁷=-0.3х⁷у⁸

3)(2а⁷х¹²)⁴ ⅛ах=2*0.125а⁷*⁴+¹х¹²*⁴+¹=0.25а²⁹х⁴⁹

4)3а³3(2а²-4)=3а³(6а²-12)=18а⁵-36а³

5)(3а²-11а+4)-(6а²-2а-3)= -18а⁴+6а³+9а²+66а³-22а²-33а-24а²-8а-12=18а⁴+72а³-17а²-41а-12
