Question

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

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

Answer 1

Answer: (B)

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