How to Solve Exponential Equations Using `ln`?
- Begin with an equation in the form \( a^x = b \), where \( a \) and \( b \) are constants.
- Take the natural logarithm `(ln)` of both sides: \( \ln(a^x) = \ln(b) \).
- Utilize the property \( \ln(a^x) = x \cdot \ln(a) \) to bring the exponent down: \( x \cdot \ln(a) = \ln(b) \).
- Isolate \( x \) by dividing both sides by \( \ln(a) \): `x = \frac{\ln(b)}{\ln(a)}`.
