Question

efetue as multiplicações

Answer 1

$i) {8}^{2} x {y}^{3} \times 2 {x}^{3} y {}^{2} \\ 16 {}^{2} {x}^{4} y {}^{5} \\ 256 {x}^{4} {y}^{5}$
$j) \: 8 {m}^{3} {n}^{2} \times 5 {m}^{5} \\ 40 {m}^{8} {n}^{2}$
$k)2 {x}^{3} y \times 5x {}^{2}z \\ 10 {x}^{5} yz$
$l)3 ( - 8xy) \\ - 24xy$
$m)6 {x}^{2} 4 {x}^{3} y \\ 24 {x}^{5} y$
