Start with an exponential expression. You have a Base, an Exponent and a Number
B^E=N
With a logarithm, you still have a Base, Exponent and Number, just arranged differently.
log (base B) Number = Exponent
So looking at the expressions...
log (base 2) 1/16=-4
log (base 3) 243 = 5
log (base 49) 7 = 1/2

A logarithm is a FUNCTION which is an exponent of a following expression

It would be log₃(243) = 5
