Read a Logarithm as an Exponent Question
A logarithm log_b(A) asks which exponent on b yields A.

Open lesson 1Algebra2: Logarithms and Exponential Equations
Logarithms reverse exponentiation with a valid positive base other than one. They answer exponent questions, reorganize multiplicative structure and solve exponential relationships while requiring positive real logarithm arguments.
Before you begin
- Evaluate integer powers; solve linear equations; recognize positive and nonzero restrictions.
Choose by skill rather than age alone. Read with an adult when useful, revisit a lesson, or explore another grade.
