WebThe problem with (-5)^x is that it's only defined at a few select points, because values like (-5)^ (1/2) are complex or imaginary, and ln of negative numbers is a bit complex (pun unintended). Thus, (-5)^x is undifferentiable over the reals; however, its derivative can still be found over the complex numbers as (-5)^x * (ln (5) + iπ). 3 comments WebNov 10, 2024 · Example 7.1.1: Calculating Derivatives of Natural Logarithms Calculate the following derivatives: d dx(ln(5x3 − 2)) d dx((ln(3x))2) Solution We need to apply the chain rule in both cases. d dx(ln(5x3 − 2)) = 15x2 5x3 − 2 d dx((ln(3x))2) = 2(ln(3x)) ⋅ 3 3x = 2(ln(3x)) x Exercise 7.1.1 Calculate the following derivatives: d dx(ln(2x2 + x))
