Question 231

Multiple Choice

Use logarithmic differentiation to find the derivative of y.
- y=x(x9) x3+53y = \sqrt [ 3 ] { \frac { x ( x - 9 ) } { x ^ { 3 } + 5 } }


A) 13x(x9) x3+53(1x+1x93x2x3+5) \frac { 1 } { 3 } \sqrt [ 3 ] { \frac { x ( x - 9 ) } { x ^ { 3 } + 5 } } \left( \frac { 1 } { x } + \frac { 1 } { x - 9 } - \frac { 3 x ^ { 2 } } { x ^ { 3 } + 5 } \right)
B) 13(lnx+ln(x9) ln(x3+5) ) \frac { 1 } { 3 } \left( \ln x + \ln ( x - 9 ) - \ln \left( x ^ { 3 } + 5 \right) \right)
C) 1x+1x93x2x3+5\frac { 1 } { x } + \frac { 1 } { x - 9 } - \frac { 3 x ^ { 2 } } { x ^ { 3 } + 5 }
D) 3x(x9) x3+53(1x+1x93x2x3+5) 3 \sqrt [ 3 ] { \frac { x ( x - 9 ) } { x ^ { 3 } + 5 } } \left( \frac { 1 } { x } + \frac { 1 } { x - 9 } - \frac { 3 x ^ { 2 } } { x ^ { 3 } + 5 } \right)
