Final answer:
To differentiate the function g(x) = (x^(-5) + 3)(x^(-3) + 5), apply the product rule and the power rule, then simplify and combine the terms to find the final derivative.
Step-by-step explanation:
To differentiate the function g(x) = (x^(-5) + 3)(x^(-3) + 5):
- Apply the product rule, which states that if f(x) = u(x)v(x), then f'(x) = u'(x)v(x) + u(x)v'(x).
- Take the derivative of the first term, (x^(-5) + 3), using the power rule, which states that if f(x) = x^n, then f'(x) = nx^(n-1).
- Take the derivative of the second term, (x^(-3) + 5), using the power rule.
- Simplify the expressions and combine the terms to get the final derivative.
The correct answer is g'(x) = -8x^(-7) - 25x^(-6) - 9x^(-4), so option A is the correct choice.
