Derivative of a number to the power of x
WebFor a power function f ( x) = x p, with exponent p ≠ 0, its derivative is (1) f ′ ( x) = d f d x = p x p − 1. (For fractional p, we may need to restrict the domain to positive numbers, x > 0, … WebIf n is a positive integer, the power rule says that the derivative of x^n is nx^ (n-1) for all x, whether you are thinking of derivatives at a point (numbers) or derivatives on an interval (functions). This can be derived using the binomial theorem or product rule.
