Root laws math
Weba0 = 1. Example: 5 0 = 1, 12 0 = 1, y 0 = 1. Rule 2: If the index is a negative value, then it can be shown as the reciprocal of the positive index raised to the same variable. a-p = 1/ap. Example: 5 -1 = ⅕, 8 -3 =1/8 3. Rule 3: To multiply two variables with the same base, we need to add its powers and raise them to that base. Web7 Sep 2024 · Root law for limits: lim x → a f ( x) n = lim x → a f ( x) n = L n for all L if n is odd and for L ≥ 0 if n is even. We now practice applying these limit laws to evaluate a limit. …
