It is very important to get the hang of these because it lays the foundation for more advanced topics, such as logarithms and roots.
There are two parts to an exponent: the base and the value of the exponent itself. Laid out like this, it is easy to see why exponents can be simplified.
You'll see that it's not too difficult; you just need to make use of one other mathematical operation in order to solve your problems.
Solving for your variable, usually x, is pretty straightforward when your x can easily be isolated through addition, subtraction, multiplication, or division.

Try it risk-free Read this lesson to learn the steps you need to take to solve exponential equations.
x = bx This property only applies when your bases are the same.
Use the standard log with a base of 10 when working with base 10 numbers.
If you see an e, then use the natural logarithm, the logarithm with a base of e.
You'll use the same methods that you use to solve all your other algebra problems with the addition of the log function helping you to take the variable out of the exponent.
