Answer 1

Ответ:

5.

$( {x}^{3})^{4} \times {x}^{7} = {x}^{7} \times {x}^{7} = {x}^{14} \\ ( {y}^{3})^{7} \div ( {y}^{5})^{4} = {y}^{10} \div {y}^{9} = {y}^{}$

3.

$1) {p}^{2} {p}^{5} = {p}^{7} \\ 2) {a}^{9} {a}^{7} = {a}^{2}$

4.

$( - 0.2) ^{3} = - 0. {2}^{3} \\ - (\frac{3}{5}) \: \times {5}^{2} = 0.6 \times {5}^{2} = {3}^{2} = 9$
