Question 1210362
.
find the domain of f (x) = (7^(x - 3))^1/(x - 1)
~~~~~~~~~~~~~~~~~~~~~~~~~



I think that the function in this problem is


        f(x) = {{{(7^(x-3))^(1/(x-1))}}},


which should be written in the HTML-format as


        f(x) = (7^(x-3))^(1/(x-1)),


so a pair of parentheses in the post is missed.


Otherwise, the formula defining the function looks strange and unnatural.


If it is so, then the only restriction for the formula is x =/= 1.
