निम्न के मान ज्ञात कीजिए ।
(i) `(2x+y)(4x^(2)-2xy+y^(2))`
(ii) `((x)/(2)-2y)((x^(2))/(4)+xy+4y^(2))`

Explanation

(i) यहाँ, `(2x+y)(4x^(2)-2xy+y^(2))=(2x+y)[(2x)^(2) - (2x)(y) + (y)^(2)]`
`= (2x)^(3) + (y)^(3) = 8x^(3) + y^(3)`
(ii) यहाँ, `((x)/(2)-2y)((x^(2))/(4)+xy+4y^(2))=((x)/(2)-2y)[((x)/(2))^(2)+((x)/(2))(2y)+(2y)^(2)]`
`= ((x)/(2))^(3) - (2y)^(3) = (x^(3))/(8) - 8y^(3)`
