## Calculus, 10th Edition (Anton)

=$24x^{7}+2$
Use the power rule for derivatives ([$x^{n}]'=nx^{n-1}$) and the rule that the derivative of the sum of the functions is the sum of the derivatives of each of the functions. Also, the derivative of a constant is 0, so the derivative of 1 is 0. Therefore, the answer is $3(8)x^{7}+2=24x^{7}+2$.
