$2) - 0.2 {a}^{2} {b}^{4} \times 5 {a}^{2} {b}^{5} = ( - 0.2) \times 5 \times {a}^{2 + 2} \times {b}^{4 + 5} = - {a}^{4} {b}^{9} \\ 3)(0.25 {x}^{ - 2} {y}^{ - 1} ) {}^{ - 3} = ( \frac{1}{4 \times {x}^{2} \times y} ) {}^{ - 3} =(4 {x}^{2} y) {}^{3} = 64 {x}^{6} {y}^{2}$

$0.2)3) \frac{ {0.4}^{11} }{ {0.4}^{4} \times {0.4}^{3} } = \frac{ {0.4}^{11} }{ {0.4}^{4 + 3} } = \frac{ {0.4}^{11 } }{ {0.4}^{7} } = {0.4}^{11 - 7} = 0.4 {}^{3} \\ 5) {9}^{0} \div {9}^{ - 2} = 1 \div \frac{1}{9 {}^{2} } = 1 \times 81 = 81 \\ 6) {7}^{8} \times {7}^{5} \times {7}^{6} = {7}^{8 + 5 + 6} = {7}^{19}$

$0.3)1) - 0.4 {x}^{2} y \times ( - 10x {y}^{2} ) = {( - 0.4) \times ( - 10)} \times {x}^{2 + 1} \times {y}^{1 + 2} = 4 {x}^{3} {y}^{3}$
