1.4)

$a {}^{12} \div {a}^{4} = {a}^{12 - 4} = a {}^{8}$

1.5)

$- 1 \frac{3}{5} {m}^{4} n {}^{3} \times ( - \frac{1}{2} {m}^{3} {p}^{6} ) {}^{3} = \\ \frac{8}{5 \times 8} m {}^{4 + 3 \times 3} n {}^{3} p {}^{6 \times 3} = \\ \frac{1}{5} {m}^{13} n {}^{3} p {}^{18} = 0.2{m}^{13} n {}^{3} p {}^{18}$

1.6)

$- 0.6x - 26x {y}^{2} - 74x {y}^{2} = \\ - 0.6x + ( - 26 - 74)x {y}^{2} = \\ - 0.6x - 100x {y}^{2}$
