Which logarithmic equation is equivalent to L^m = E

Question

1) LogL E = m
2) logE L = m
3) logm E= L
4) logE m= L

Answer 1

I had my students memorize this pattern

2^3 = 8 <-----> log₂ 8 = 3

That way you can tell which parts go where.
What do you think?

Answer 2

LogE l=m

Answer 3

1) LogL E = m
