Answer 1

Ответ:

$(8a {}^{2} - b {}^{4} c {}^{3} ) {}^{3} = 512a {}^{6} - 192a {}^{4} b {}^{4} c {}^{3} + 24a {}^{2} b {}^{8} c {}^{6} - b {}^{12} c {}^{9}$

$(9x {}^{4} y {}^{3} z {}^{7} ) {}^{2} = 81x {}^{8} y {}^{6} z {}^{14}$

$( - 1.2x {}^{5} y {}^{7} z {}^{7} ) {}^{2} = \frac{36}{25} x {}^{10} y {}^{14} z {}^{14}$
