A Brief Review of Logarithms
“The exponent to which base b must be raised to get x is y.”
The Most Useful Property of Logarithms
But… WHY??!!!
The exponent to which base b must be raised to get xt is exactly the same as t times the exponent to which base b must be raised to get x.
A more formal “proof”…
