Learn how to solve power rule problems step by step online. Find the derivative (d/dx)(x^2) using the power rule. The power rule for differentiation states that if n is a real number and f(x) = x^n, then f'(x) = nx^{n-1}. Subtract the values 2 and -1. Any expression to the power of 1 is equal to that same expression.
