Let (x+y)^(p+q) = x^p · y^q. If p + q = 10, then dy/dx is equal to:
Answer
The correct answer is A: y/x. As established, for the equation (x+y)^(p+q) = x^p·y^q, dy/dx = y/x regardless of p, q values.
- A.y/x✓ Correct
- B.xy
- C.x¹⁰y¹⁰
- D.(y/x)¹⁰
As established, for the equation (x+y)^(p+q) = x^p·y^q, dy/dx = y/x regardless of p, q values.
