SUMMARY

The derivative of the function \( (1+4x)^5(3+x-x^2)^8 \) requires the application of both the product rule and the chain rule. The correct differentiation yields the expression \( 5(1+4x)^4(4)(3+x-x^2)^8 + 8(3+x-x^2)^7(1-2x)(1+4x)^5 \). It is crucial to ensure that both rules are applied correctly to avoid computational errors. Additionally, using LaTeX for mathematical expressions enhances clarity and presentation.

PREREQUISITES
  • Understanding of the product rule in calculus
  • Familiarity with the chain rule in calculus
  • Knowledge of polynomial differentiation
  • Ability to use LaTeX for mathematical notation

The Attempt at a Solution



I get to this point, but I don't know how to break it down.

5(1+4x)^4(4x)(3+x-x^2)^8+8(3+x-x^2)(1-2x)

The multiplication and the chain rules must be both applied. Your computations either forgot one of the 2, or used them wrongly.

Please, check again.

And BTW, you can use LaTeX to write down your formulas in an elegant and comprehensible fashion. Just type the standard code between the [itex][tex]\, \mbox{and} \,[/tex][/itex][tex][/tex] tags.
