Multiple choice general knowledge math & puzzles d/dx(1/u^n) = (^ is Power) -(v/u^n+1)dy/dx (n/n^u+1)dv/dx -(n/u^n+1)du/dx None of the above Reveal answer Fill a bubble to check yourself C Correct answer Explanation Using the power rule for differentiation, d/dx(u^-n) = -n * u^(-n-1) * du/dx. This simplifies to -(n/u^(n+1)) * du/dx. The other options either use the wrong variable (v), incorrect power notation, or omit the chain rule component (du/dx).
