Ответ:

$1) \: 1.5 \times 6 {}^{2} - 2 {}^{3} = 1.5 \times 36 - 8 =54 - 8 = 46 \\ 2)a)x {}^{8} \times x {}^{2} = x {}^{8 + 2} = x { }^{10} \\ b)x {}^{8} \div x {}^{2} = x {}^{8 - 2} = x {}^{6} \\ c)(x {}^{8} ) {}^{2} = x {}^{8 \times 2} = x {}^{16} \\ \\ d) \frac{(x {}^{4}) {}^{5} \times x {}^{2} }{x {}^{12} } = \frac{x {}^{4 \times 5} \times x {}^{2} }{x {}^{12} } = \frac{x {}^{20} \times x {}^{2} }{x {}^{12} } = \\ = x {}^{20 + 2 - 12} = x {}^{22 - 12} = x {}^{10}$
