During my childhood, In 5th class my maths teacher had written on the blackboard that any variable to the power of 0 exponent is one. She then asked the class 'if there was anyone in the class who could prove this?' In a split second I got up and wrote on the blackboard Y x Y x Y / Y x Y x Y which is Y to the power three divided by Y to the power three. Further Y to the power 3-3 or Y to the power 0. Then I cancelled each Y in the first expression to show it is equal to 1. Sometimes are wish to solve challenges teaches us far more than conventional methods. | During my childhood, In 5th class my maths teacher had written on the blackboard that any variable to the power of 0 exponent is one.
