Answer:
a.
Step-by-step explanation:
First step is ti distribute the exponent outside the parenthesis. According to the law of exponents, you need to distribute it to each variable.
Now again, following the law of exponents, if you have negative exponents, you put them in the opposite side of the fraction.
Next, when it comes to division, we subtract the exponents of the numerator and the denominator of similar variables.
Since the exponent of x is negative, we move it below the fraction.
