Question

Factorize 64m3-343n3.

Answer 1

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}

Answer 2

Hiii


Your question can be factorie by using formula of a^3-b^3 =(a-b)(a^2+ab+b^2)

=(4m-7n)(16m^2+28mn+49m^2)


hope its help you
