If dimensions of A and B are different, then which of the following operation is valid?
A/B
e^(-A/B)
A-B
A+B
In eˣ, x must be dimensionless so in e^(-A/B), A & B must have same dimensions also A + B and A – B are not possible because quantities with different dimensions can’t be added or subtracted.
