Answer 1

${\huge{\underline{\underline{\sf{\red{Solution:-}}}}}}$

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

${64m}^{3} + {n}^{3} = ( {4})^{3} + ( {n})^{3}$

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

$= (4m + n)(( {4m})^{2} - 4m \times n + ({n})^{2})$

$= (4m + n)( {16m}^{2} - 4mn + {n}^{2} )$

Answer 2

Answer:

64m³ - 343n³ = (4m)³ - (7n)³. Use, formula, a³ - b³ =( a - b)(a² + ab + b²) = (4m - 7n) {(4m)² + (4m)(7n) + (7n)² } = (4m - 7n) {16m² + 28mn + 49n²}.
