Questions & Step-by-Step Solutions

What is the derivative of x^3?
  • Step 1: Understand that the derivative measures how a function changes as its input changes.
  • Step 2: Identify the function we are working with, which is x^3.
  • Step 3: Use the power rule for derivatives, which states that if you have x^n, the derivative is n*x^(n-1).
  • Step 4: In our case, n is 3 because we have x^3.
  • Step 5: Apply the power rule: Multiply the exponent (3) by the base (x) raised to the exponent minus one (3-1).
  • Step 6: Calculate: 3 * x^(3-1) = 3 * x^2.
  • Step 7: Write the final answer: The derivative of x^3 is 3x^2.
