The rule for integration by parts is derived from the product rule. If m and n are natural numbers such that m n is a reduced fraction, and a is any non-negative real number or function that takes non-negative values, then am n = n√am = (n√a)m. Additionally, if n is an odd natural number, then even when a is negative, we still have am n = n√am = (n√a)m. Look for perfect cubes in the radicand, and rewrite the radicand as a product of factors. And again, your n number is just the index of your radical. Simplify the square root of the perfect square. That is, the product of two radicals is the radical of the product. One special case of the product rule is the constant multiple rule, which states that if c is a number and f(x) is a differential function, then cf(x) is also differential, and its derivative is (cf)'(x)=cf'(x). nators.
