41 Logarithms Part 1
When we say log base b of x equals y, we are saying b to the y equals x.
With logs, the base of the log raised to the power of what's on the other side of the equal sign will equal the number that the log is operating on.

Exponentiation
b˄n is called "b raised to the n-th power", "b raised to the power of n", "the n-th power of b", "b to the n-th", or most briefly as "b to the n"

Logarithms Explained
Anytime you see log base b of some number n, you can think about it as asking the question "What power do I need to put in my exponent to get b to that power equal to this number n?"
