Question

а)(-10x^2y)^3•0,0001y^3x;
б)-3a^3b^2c)^3•(0,2a^2bc)^2.
P.S ответ и решение обизательны

Answer 1

Ответ:

$( - 10x {}^{2} y) {}^{3} \times 0.0001y {}^{3} x = - (10x {}^{2} y {}^{3} \times 0.0001y {}^{3} x = - 1000x {}^{6} y {}^{3} \times 0.0001y {}^{3} x = - 0.1x {}^{7} y {}^{6}$

$(- 3a {}^{3} b {}^{2} c) {}^{3} \times(0.2a {}^{2} bc) {}^{2} = - 3a {}^{3} b {}^{2} c \times 0.2 {}^{2} \times a {}^{4} b {}^{2} c {}^{2} = - 3a {}^{3} b {}^{2} c \times ( \frac{1}{5} ) {}^{2} \times a {}^{4} b {}^{2} c = - 3a {}^{3} b {}^{2} c \times \frac{1}{25} a {}^{4} b {}^{2} c = - \frac{3}{25} a {}^{7} b {}^{4} c {}^{3}$
