Apply Power Rule: To find the derivative of the function x81 with respect to x, we will use the power rule for derivatives. The power rule states that the derivative of xn with respect to x is n⋅xn−1. In this case, we can rewrite x81 as x−8.
Calculate Derivative: Applying the power rule, we take the exponent −8 and multiply it by the function, then subtract 1 from the exponent to get the new power of x. So the derivative of x−8 is −8⋅x−8−1 which simplifies to −8⋅x−9.
Final Form: The expression −8x−9 can be rewritten as −x98 for clarity, which is the final form of the derivative.
