So, 

This is a general formula that you should memorize. The inverse of  is . You can use this formula to change an equation from a log function to an exponential function.

To solve this, you need to set up a logarithm.  Our exponent is .  The logarithm's base is .  The value  is the operand of the logarithm. Therefore, we can write an equation:

Now, you cannot do this on your calculator.  Therefore, using the rule for converting logarithms, you need to change:

to...

You can put this into your calculator and get:

, or rounded, 

To solve this, you need to set up a logarithm. Our exponent is .  The number of which it is the exponent of  is the base.  This is the logarithm's base.  The value  is the operand of the logarithm. Therefore, we can write an equation:

For logarithmic equations,  can be rewritten as .

In this expression,  is the base of the equation ().  is the exponent () and  is the term (). 

In putting each term in its appropriate spot, the exponential equation can be converted to .

Solve the following logarithm:

Recall that we can convert logarithms to exponential form via the following:

Using this approach, convert the given log to exponential form:

Rewrite the following expression as an exponential expression:

Recall the following property of logs and exponents:

Can be rewritten in the following form:

So, taking the log we are given;

We can rewrite it in the form:

So b must be a really huge number!

Convert the following logarithmic equation to an exponential equation:

Recall the following:

This

Can be rewritten as

So, our given logarithm

Can be rewritten as

Fortunately we don't need to expand, because this woud be a very large number!
