Question

Спростити вираз а,б,в.

Answer 1

1
$(ax)^2*2a=a^2x^2*2a=2a^3x^2$
2
$(-0,5bc)^2*(2b^2x)^3=0,25b^2c^2*8b^6x^3=2b^8c^2x^3$
3
$(-0,6ay^2)^3*(-10/3*a^2by)=-0,216a^3y^6*(-1000/27)*a^6b^3y^3=$$8a^9y^9b^3$

Answer 2

A) (ax)^2 *2a = a^2 *x^2 * 2*a = 2a^3 * x^2
б) (-0.5bc)^2 * (2b^2 *x)^3 = (-0,5)^2 * b^2 * c^2 * 2^3 * b^6 *x^3 = 0.25*8*b^8 *c^2 * x^3 = 2b^8 * c^2 *x^3 - конечный ответ.
в) (-0.6ay^2)^3 * (-10/3 *a^2by)^3 = -0.216 *a^3 * y^6 *(-1000/27)*a^6 *b^3 *y^3 = 8a^9 *y^9 *b^3
