Please help me understand this in detail and also please tell me the math rules that allows for this.
I know that
Y/Y^a equals to Y^(1-a) this is allow by the rule of exponents X^a/X^b = X^(a-b)
Does the same rule apply to this? - If not, please provide the steps to get answer
Y^a/Y equals 1/Y^(1-a)
It explains the rule of exponents
