Why does 10^log(50) equal 50? I understand that 10^log(x) cancel each other out and leave you with x, but I don't understand why.

To write the expression log(x) is to ask, "Ten to the power of what equals x?"
So, 10^log(50) is "Ten to the power of whatever would equal 50 if ten was taken to the power of it".
Therefore, it's 50 by definition.

It's the very definition of log. It's like asking "why is sqrt(3) ^2 = 3?" or "why is 70 / 5 * 5 = 70?"

or to be specific, it's the very definition of log base 10, which your classes seem to be using as the default

it's very common to use log base 2 or base e as well, though logarithms can have any number as a base
