E ∩ F = {}
Step-by-step explanation:
Intersection is an operation performed on sets. In intersection, the common elements of the sets involved are written,
Given
E = {1, 2, 3}
F = {101, 102, 103, 104}
We have to find the intersection of both sets as indicated
So,
E ∩F = {1, 2, 3} ∩ {101, 102, 103, 104}
E ∩ F = {}
As there are no common elements in both sets the intersection will be an empty set

It's a repeating decimal.
Here are some solutions: (there are actually an infinite amount of them)
x = 0 , y = 7
x = 1 , y = 8
x = 2 , y = 9
x = 3 , y = 10
x = 4 , y = 11
x = 42 , y = 49
x = pi , y = pi + 7
which means
has no solution, and we can omit that factor.
This leaves us with
which occurs for
