Question

The derivative of function $6 x^{100}-x^{55}+x$ is

• A. $600 x ^{100}-55 x ^{55}+ x$
• B. $600 x^{99}-55 x^{54}+1$
• C. $99 x^{99}-54 x^{54}+1$
• D. $99 x^{99}-54 x^{54}$

Answer 1

Answer: (B)

If given function is $6 x^{100}-x^{55}+x.$
Then, the derivative of function is $6.100.x^{99}-55.x^{54}+1$
or $600 x^{99}-55 x^{54}+1$
