RE: Why is the 0 exponent of a non-zero number equal to 1?
Assuming we have two variables x^a and x^b.
If we multiply the two, following the multiplictive rule would be
x^[a+(-b)] = x^(a-b)
No. Ιt's multiplication, we sum exponents in this case.
x^a * x^b=x^(a+b), and therefore if a=b, then x^a * x^b= x^2a (or x^2b)
This example you used works in case we divide those variables x^a and x^b (or you probably forgot the minus sign on the b exponent).
Regardless, upvoted. Good job!
You are right, it is division. Thank you for pointing it out.
Noted. thanks for pointing that out.
