What in the world is the "logaritmeregneregel".
Some soft of mathematical rule. Can someone explain it to me? Either danish or english.

you can "extract" power of a number from the log func in front of it (because log is a power and you can skip step of exponentiation, and after log just multiply by additional power)
example:
log 3 (x^2) = 10, so
3^(10) = x^2
x = +-3^(10/2)
OR
log 3 (x^2) = 10
2 * log 3 (x) = 10
log 3 (x) = 10/2
3^(10/2) = x
NOTE: x must be > 0

Thanks for the clear explanation mein freund. The power rule makes sense too.
I've got another one that says: "Is x=2 a answer to this equation"
