Wrath of Math | Use One-to-One Property to Solve Logarithmic Equations | Precalculus Exercises @WrathofMath | Uploaded 2 months ago | Updated 5 hours ago
We go over how to use the one-to-one property of logarithms to solve basic logarithmic equations. If two logs are equal and have the same base, by the one to one property, their inputs must be equal. By using this property and setting inputs equal to each other, we can solve for the unknown. #precalculus
