First let's reduce the fraction. Reduced fractions are usually easier to work with. Since 2 is a common factor we can reduce the fraction be a factor of 2:
From this point there are, as usual, a number of ways we can go. The most direct way to the answer is to multiply the numerator and denominator by . (I hope you can see that this will turn the denominator into a 1 which, in turn, means that we will no longer have a fraction. And not having a fraction anymore is, I hope you agree, a good thing.):
In the denominator, since
the rule for exponents when you multiply is to add the exponents, and
-4/3 + 4/3 = 0, and
the denominator becomes a 1!
Now let's simplify using the Distributive Property:
Again we'll use the "add the exponents when multiplying" rule:
And we're finished!
