# Solve for x when x is an exponent

How to solve problems like 3 (raised to the x power) = 5, using base 10 logarithms.

## Exponential Equations

The problem here is that the x x is in the exponent. Because of that all our knowledge about solving equations wonâ€™t do us any good. We need a way to get the x x out of

## Solving Exponential Equations

log.15=log.85^x (remember that when there is an exponent in a logarithm, it is moved in front of the log as a multiplier) log (.15)= x log (.85) x= log (.15)/log (.85) x=11.6732. And now plug the number in for x to check if the
