Questions & Step-by-Step Solutions

What is the derivative of f(x) = x^5?
  • Step 1: Identify the function you want to differentiate. In this case, the function is f(x) = x^5.
  • Step 2: Use the power rule for differentiation. The power rule states that if you have x raised to a power n, the derivative is n * x^(n-1).
  • Step 3: Apply the power rule to f(x) = x^5. Here, n = 5.
  • Step 4: Multiply the exponent (5) by the coefficient (which is 1 for x^5) to get 5.
  • Step 5: Decrease the exponent by 1. So, 5 - 1 = 4.
  • Step 6: Combine the results from Step 4 and Step 5. This gives you the derivative: f'(x) = 5x^4.
