How it works
Solve for x in the exponential equation bˣ = c.
Who it's for: Algebra and pre-calculus students working with logarithms.
Solution: x = ln(c) / ln(b).
Requires base b > 0, b ≠ 1, and c > 0.
Handles common bases like 2, 10, and e.
How to use
- Enter base b and value c.
- Read x as the exponent that satisfies bˣ = c.
