Power Rule
One of the most important differentiation rules is the power rule. This rule applies when we have functions containing our variable to a numerical exponent, regardless of if that exponent is positive, negative, an integer, or a fraction. This rule states that {eq}\frac{d}{dx} x^n = nx^{n-1} {/eq}.
