Question

нужно, завтра сдавать нужно!

Answer 1

1) а)

$35a \times 2 {a}^{2} = 70 {a}^{3}$

б)

$- 4 {x}^{3} \times 5 {x}^{2 \times 3} = - 4 {x}^{3} \times 5 {x}^{6} = - 20 {x}^{9}$

в)

${( - 4)}^{3} {y}^{2 \times 3} \times {y}^{5} = - 64 {y}^{6} \times {y}^{5} = - 64 {y}^{6 + 5} = - 64 {y}^{11}$

2) а)

$( - \frac{1}{8} {x}^{2} {y}^{3} ) \times {2}^{4} {x}^{6 + 4} {y}^{4} = ( - \frac{1}{8} {x}^{2} {y}^{3} ) \times 16 {x}^{10} {y}^{4} = - 2 {x}^{2 + 10} {y}^{4} = - 2 {x}^{12} {y}^{4}$

б)

$90 {a}^{4} {b}^{3} \times {( - \frac{10}{3} )}^{2} {a}^{2} {b}^{6 + 2} = 90 {a}^{4} {b}^{3} \times ( - \frac{100}{9}) {a}^{2} {b}^{8} = 1000 {a}^{4 + 2} {b}^{3 + 8} = 1000 {a}^{6} {b}^{11}$
