SUMMARY

The differentiation problem presented involves the expression (3x+2)5(x+1)-2. The correct approach to differentiate this expression is to apply the Product Rule, as confirmed by multiple contributors in the discussion. The derivative is calculated as dy/dx = 15(3x+5)4 * -2(x+1)-3, which simplifies to -30(3x+5)4(x+1)-3. The initial confusion regarding the use of the Product Rule was clarified, emphasizing its necessity for this type of problem.

PREREQUISITES
  • Understanding of calculus concepts, specifically differentiation.
  • Familiarity with the Product Rule for derivatives.
  • Knowledge of polynomial and rational functions.
  • Ability to manipulate algebraic expressions.
NEXT STEPS
  • Study the Product Rule in detail, including examples and applications.

Homework Statement



(3x+2)^5.(x+1)^-2

Homework Equations



dy/dx = dy/du . du/dx

The Attempt at a Solution



y=(3x+5)^5 . (x+1)^-2

u = 3x + 5 , du/dx = 3
v = u^5 , dv/du = 5u^4
= 15(3x+5)^4

u = x + 1 , du/dx = 1
v = u^-2 , dv/du = -2u^-3
-2(x+1)^-3


dy/dx = 15(3x+5)^4 . -2(x+1)^-3

Correct or not? or should I use the Product Rule. . .

=5(3x+5)^4 .
