Question

factors of 64mcube - 343ncube​

Answer 1

Answer:

(4m-7n),(16m²+28mn+49n²) are thr factors of 64m³-343n³

Step-by-step explanation:

64m³-343n³

(4m)³-(7n)³

[Using identity a³-b³=(a-b) (a²+ab+b²)

(4m-7n)(16m²+28mn+49n²)

So, the factors are (4m-7n),(16m²+28mn+49n²)

Answer 2

Answer:

(4m - 7n) and (16m² + 49n² + 28mn)

Step-by-step explanation:

here , 64m³ - 343n³

also,. 64 = 4³

343 = 7³

so,. (4m)³ - (7n)³

using a³-b³ = (a-b)( a² + b² + ab)

so, (4m)³ - (7n)³ = (4m-7n) ( 16m² + 49n² +28mn)

so its factors are ( 4m- 7n ) and

( 16m²+49n² + 28 mn )

hope it works
