A) 12
B) 33
C) 9
D) 15
Correct Answer: B
Solution :
\[y=\left( \left( \left( x \right) \right) \right)+{{\left( \left( x \right) \right)}^{2}}\] \[\frac{dy}{dx}='\left( \left( \left( x \right) \right) \right)'\left( \left( x \right) \right)'\left( x \right)+2\left( x \right)'\left( x \right)\] \[='\left( 1 \right)'\left( 1 \right)'\left( 1 \right)+2\left( 1 \right)'\left( 1 \right)\] \[=3\times 5\times 3+2\times 1\times 3\] \[=27+6\] \[=33\]
