Derivative of \(x^x\) with respect to \(x\) \(log\) \(x\) is
- A \(x\)
- B \(x\) \(log\) \(x\)
- C \(x^x\)
- D \(log\) \(x\)
Answer & Solution
Correct Answer
(C) \(x^x\)
Step-by-step Solution
Detailed explanation
Let \(u = x^x\) and \(v = x \log x\). \(\frac{du}{dx} = x^x (1 + \log x)\) \(\frac{dv}{dx} = 1 \cdot \log x + x \cdot \frac{1}{x} = \log x + 1\) \(\frac{du}{dv} = \frac{du/dx}{dv/dx} = \frac{x^x (1 + \log x)}{1 + \log x} = x^x\)

Theory of Evolution
The evolution of life is a gradual process through which simple organisms are transformed into complex life forms over billions of years. It involves genetic changes, adaptation to the environment, and the emergence of diversity in species. Fossil records provide evidence of extinct life forms and transitional stages. Evolution is influenced by factors such as mutation, genetic recombination, and environmental pressure, shaping the biodiversity we see today. Charles Darwin and Alfred Russel Wallace were pioneering naturalists who developed the theory of evolution by natural selection.
