Find the following products: (i)(6x)/5(...

Find the following products: (i)`(6x)/5(x^3+y^3)`
(ii)`x y(x^3-y^3)`
(iii)`0. 1 y(0. 1 x^5+0. 1 y)`

Text Solution

Verified by Experts

(i)`(6x)/5(x^3+y^3)`
`=(6x^4)/5+(6xy^3)/5`

(ii)`x y(x^3-y^3)`
`=x^4y-y^4x`

(iii)`0. 1 y(0. 1 x^5+0. 1 y)`
`=0.01x^5y+0.01y^2`
