Question

. Factorise : (x15 - 64y3)​

Answer 1

Answer:

According to the question  (x^5 + 4y)  •  [ ( x^10 ) - (4x^5)y + (16y^2) ]

Step-by-step explanation:

(x15 - 64y3)​

= (x^15) +  (2^6 * y^3)

= (x^5)^3 + (4y)^3

=   (x^5 + 4y)  •  [ ( x^10 ) - (4x^5)y + (16y^2) ] [ as we know (a^3 + b^3) =  (a+b) • (a^2-ab+b^2)]

So, the correct answer is   (x^5 + 4y)  •  [ ( x^10 ) - (4x^5)y + (16y^2) ]
