Answer 1

Объяснение:

${0.2}^{10} \times {5}^{12} = \\ = {0.2}^{10} \times {5}^{10} \times {5}^{2} = \\ = (0.2 \times 5) ^{10} \times 25 = \\ = {1}^{10} \times 25 = 25$

$1) = (9 {x} {y}^{2} ) ^{2}$

$2) = - (10 {x}^{2} {y}^{4} ) ^{2}$

$3) = ( - 5) \times ( - \frac{1}{5}) \times {x}^{3 + 5} \times {y}^{5 + 3} = \\ = {x}^{8} {y}^{8} = {( {x}^{4} {y}^{4} )}^{2}$

$4) = 27 {x}^{3} {y}^{3} \times 27 {y}^{6} = \\ = {27}^{2} {x}^{3} {y}^{9} = \\ = (27x ^{ \frac{3}{2} } {y}^{ \frac{9}{2} } ) ^{2}$
