Answer:
x = 10^10
Step-by-step explanation:
You are right to question the question. As posed, it makes no sense.
The idea of an x-intercept is applicable to a relation involving two variables that can be graphed on a coordinate plane.
If you graph this equation on an x-y plane, it will be a vertical line at x = 10^10, so that would be the x-intercept.
_____
I suggest you ask for an explanation from your teacher.
_____
The graph of y=log(x) is something else entirely, as you know. The x-intercept of that graph is x=1.
