The multiplicative law of indices states that
xa * xb = xa+b
Now, if you put b = 0 in that equation you get
xa * x0 = xa+0
But a+0 = a so the right hand side is simply xa
Which means, the equation becomes
xa * x0 = xa
This is true for any x.
That is, multiplying any number by x0 leaves it unchanged.
By the identity property of multiplication, there is only one such number and that is 1.
So x0 must be 1.
