**Exponential functions**

An exponential function is the inverse of a logarithmic function. In this case, the unknown variable is the exponent. The exponential function is in the form of

where * a* is positive and different from 1. If

*= 1, then this would be a constant function of 1.*

**a**### Solving equations

Solving equations

If we can get the same base number to both sides of the equation, then this situation is optimal

If this is not possible, we use a 10-based logarithm to help us solve the equation

In some calculators you can choose the base of the logarithm. Then solving it is much quicker
