If f(x) = `e^(x)`, then `lim_(xto0) (f(x))^((1)/({f(x)}))` (where { } denotes the fractional part of x) is equal to -A. f (1)B. f (0)C. f (-`oo`)D. Does not exist

Answer» Correct Answer - D
`{c^(x)}=[{:(e^(x)-1",",xgt0^(+)),(e^(x)",",xlt0^(-)):}`
`underset(xto0^(-))(lim)(e^(x))^((1)/(e^(x)))=1`
`underset(xto0^(+))(lim)(e^(x))^((1)/(e^(x)-1))=e`
`rArr` limit does not exist at x = 0
