A) 4
B) 2
C) 5
D) 10
E) 3
Correct Answer: E
Solution :
\[{{\left[ 5+{{\left( \frac{dy}{dx} \right)}^{2}} \right]}^{5/3}}={{x}^{5}}\left[ \frac{{{d}^{2}}y}{d{{x}^{2}}} \right]\] ...(i) \[\Rightarrow \] \[{{\left[ 5+{{\left( \frac{dy}{dx} \right)}^{2}} \right]}^{5}}={{x}^{15}}{{\left[ \frac{{{d}^{2}}y}{d{{x}^{2}}} \right]}^{3}}\] \[\therefore \] \[\deg ree=3\]You need to login to perform this action.
