38+n=57 n=57-38 n=19
Using Euler's relation, we know that e^(i*n*pi) = cos(n*pi) + i*sin(n*pi) where n is an integer. We also know that we can rewrite 10 as e raised to a specific power, namely e^(ln(10)). So substituting this back into 10^i and then applying Euler's relation, we obtain 10^i = (e^(ln(10)))^i = (e^(i*ln(10))) = cos(ln(10)) + i*sin(ln(10)).

The product of 57 and 10 is equal to 57 x 10 = 570.
Longitudes cannot be N or S so it must be 30 E.
57 N 10 E is near Aalborg, Denmark
The coordinates 57N 10E are in the town of Aalborg, Denmark.
The latitude and longitude coordinates for Lascaux Caves in France are approximately 45.0514° N, 1.1859° E.
61 N 10 E is Norway.
40°38′N 22°57′E
A set of latitude/longitude coordinates defines a single point on the Earth's surface, so it's not possible for a whole country to be right there. That particular point is just outside the city of Ålborg in Denmark. Any other point in Denmark has different coordinates.
61 N 10 E is Nord-torpa, Norway.
