Question

343m³+n³factorise it​

Answer 1

Step-by-step explanation:

We know that,

x³ - y³ = (x-y) ( x² - xy + y² )

So, here

x = 4m , y = 7n

= 64m³ - 343n³ = (4m - 7n) { (4m)² + 4m*7n + (7n)² }

= 64m³ - 343n³ = (4m - 7n) { 16m² + 28mn + 49n² }

Answer 2

Answer:

We know that

x³ - y³ = (x-y) ( x² - xy + y² )

So, here

x = 4m , y = 7n

= 64m³ - 343n³ = (4m - 7n) { (4m)² + 4m*7n + (7n)² }

= 64m³ - 343n³ = (4m - 7n) { 16m² + 28mn + 49n² }
