Problem 1109
Here is a tricky puzzler. Did you know that there exists a value of x such that when x3 and x4 are calculated that together all ten digits are produced exactly once? For example, if x = 3 then 33 and 34 produce 27 and 81 which is only 4 of the 10 digits (1, 2, 7 and 8). Once you determine the value of x that satisfies this condition, enter the value of x3 for the answer?
