Hi all, so I have a question on this exponents question.

Quant A: (5^x)/(5^(x-1))
Quant B: (5^(x-1))/(5^(x-2))

x>0

The answer is that two quantities are equal.

I understand that A: 5^(x-x+1)=5 and B: 5^(x-1-x+2)=5, thus A and B are equal, but what about the case where x=1?
Then A would be 5 over zero, and B would be zero over 1/5. In this case, A and B are not equal. So should the relationship be indeterminable?
