How to Solve Exponential Equations Using Log?
- Start with an equation in the form \( a^x = b \), where \( a \) and \( b \) are constants.
- Take the logarithm of both sides of the equation using a common logarithm (log base `10`) or natural logarithm `(`log base `e)`: \( \log(a^x) = \log(b) \).
- Utilize the property \( \log(a^x) = x \cdot \log(a) \) to move the exponent in front: \( x \cdot \log(a) = \log(b) \).
- Isolate the variable \( x \) by dividing both sides by \( \log(a) \): `x = \frac{\log(b)}{\log(a)}`.
