Five whys

Five whys (or 5 whys) is an iterative interrogative technique used to explore the cause-and-effect relationships underlying a particular problem. The primary goal of the technique is to determine the root cause of a defect or problem by repeating the question "Why?" five times. The answer to the fifth why should reveal the root cause of the problem. The technique was described by Taiichi Ohno at Toyota Motor Corporation. Others at Toyota and elsewhere have criticized the five whys technique for various reasons (see ). (Wikipedia).

Why does 5^0 = 1? Why does 5^(-1) = 1/5? (zero and negative exponents)

This video tries to give a simple WHY behind two famous "rules" in mathematics: A (nonzero) number raised to the "zeroth" power equals one, and a (nonzero) number raised to the "(-1)st" power is the reciprocal.
