To simplify, we're going to use the following identities (equations that are true for all values of the given variable(s))


1. . Basically, you can either multiply first, then exponentiate, OR, exponentiate and then multiply. (note: this can expand to any number of terms inside the parenthesis. So you could have 50 terms in the parenthesis if you wanted). Example:


2. . When you raise an exponential expression to another exponent, you're going to multiply the exponents. Example:


3. . When you multiply monomials (with a common base), you're going to add the exponents. Example:


---------------------------------------

Let's use the identities shown above to simplify. I'll refer to each identity listed by the number associated with them.


Start with the given expression.


Use identity number 1 (see above) to break up the expression.


Use identity number 2.


Multiply


Group the terms with common bases (ie group all the 'x' terms together, etc.)


Use identity #3 to multiply the monomials.


Add


Square 3 to get


So simplifies to
