what can we say about the value of x, if e-x = 0 ?
in general, can we write this expression as : loge0 = -x ?
Given, e-x = 0
The given exponential isn't defined for any value of x for which it is equal to zero.
Similarly, log e 0 = -x is also undefined.
If ab = c then it can also be written as:
loga c = b
