Me with this question its ! simplify. your answer should contain only positive exponents.

Start by distributing the exponent to each of the terms in .  This will become , and .  Now, the expression is:

.

We can now simplify the bottom to read: because when multiplying variables raised to an exponent, we add the exponents.  The expression now looks like:

The 2/8 simplifies to 1/4:

Now, we have two u terms on the top and bottom.  When dividing variables raised to an exponent, we subtract the exponents.  However, since 3-5=-2, the term will be on the bottom to avoid the negative exponent.  The final answer is:

Hope this makes sense!!
