Calculate and express in the simplest form .
First determine the sign of the negative fraction raised to a power. When a negative number is raised to an even power, the result will always be even.
Then find the square of each fraction. When a fraction is raised to a power, we can raise the numerator and denominator by the same power.
The last step is to divide and write the answer in its simplest form. Remember that dividing by a fraction is the same as multiplying by the reciprocal.
