Why anything to the power 0 is eqaul to 1
It is a common identity that x0 = 1 for all x.
Here is one way in which to see why this is so.
We know
x/x = 1
but x= x1 and 1/x = x-1
x/x = x1x-1
We also know that xaxb = xa+b which gives
x/x = x1-1=x0
We initally stated that x/x = 1 and have shown x/x = x0 so
x0 =x/x = 1
so
x0 = 1
I have already seen it somethere…
