A) \[4({{x}^{2}}+\cos x)(2x-\sin x)\]
B) \[4{{({{x}^{2}}-\cos x)}^{3}}(2x-\sin x)\]
C) \[4{{({{x}^{2}}+\cos x)}^{3}}(2x-\sin x)\]
D) \[4{{({{x}^{2}}+\cos x)}^{3}}(2x+\sin x)\]
Correct Answer: C
Solution :
\[\frac{d}{dx}{{[{{x}^{2}}+\cos x]}^{4}}=4{{[{{x}^{2}}+\cos x]}^{3}}[2x-\sin x]\].You need to login to perform this action.
