Using the product rule (1×d2+2×d1), you would set 1 as x3 and 2 as (2x5)4.

The derivative of 1 would be 3x2 and the derivative of 2 is 4(2x5)32, or 8(2x5)3 using the chain rule.

Now plug in the values into the product rule, so that (x3×8(2x5)3)+((2x5)4)×3x2).

This expanded is 112x6960x5+3000x44000x3+1875x2.
