उत्तर

y = (5x3 - 4x2 - 8x)9 

Differentiating both sides w.r.t.x, we get

`"dy"/"dx" = "d"/"dx"` [(5x3 - 4x2 - 8x)9]

`= 9("5x"^3 - 4"x"^2 - 8"x")^8 * "d"/"dx" ("5x"^3 - 4"x"^2 - 8"x")`

`= 9("5x"^3 - 4"x"^2 - 8"x")^8 * [5(3"x"^2) - 4(2"x") - 8]`

∴ `"dy"/"dx" = 9("5x"^3 - 4"x"^2 - 8"x")^8 * (15"x"^2 - 8"x" - 8)`
