Final answer:
To find the derivative of the given function -9 √x + 10/x⁸, we will use the power rule and the chain rule. The derivative is -9/2√x - 80/x⁹.
Step-by-step explanation:
To find the derivative of the given function, -9√x + 10/x^8, we will use the power rule and the chain rule.
The power rule states that if we have a term of the form ax^n, then its derivative is given by d/dx(ax^n) = anx^(n-1).
Applying the power rule to the first term, we get that the derivative of -9√x is -9/2√x.
For the second term, we can rewrite it as 10x^(-8) and apply the power rule to get that the derivative is -80/x^9.
Thus, the derivative of -9√x + 10/x^8 is -9/2√x - 80/x^9.
