Question

quien me ayuda porfa​

Answer 1

Respuesta:

$9 {x}^{4} - 64 {y}^{6} =$

${3}^{2} {x}^{4} - 64 {y}^{6 } =$

${3}^{2} {x}^{2 \times 2} - 64 {y}^{6}$

${3}^{2} {x}^{2 \times 2} - {8}^{2} {y}^{6} =$

${3}^{2} {x}^{2 \times 2} - {8}^{2} {y}^{2 \times 3} =$

${3}^{2} \times ( {x}^{2} {)}^{2} - {8}^{2}{y}^{2 \times 3}$

${3}^{2} \times ( {x}^{2} {)}^{2} - {8}^{2} \times ( {y}^{3} {)}^{2} =$

$( {3x}^{2} {)}^{2} - {8}^{2} \times ( {y}^{3} {)}^{2} =$

$( {3x}^{2} {)}^{2} - ( {8y}^{3} {)}^{2} =$

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