This and the next few problems are exercises in writing rational expressions in standard form. You are asked to enter the numerator and denominator as polynomials. For example, since we carry out divisions by increasing length of the fraction bar (as discussed in class), $$\frac{~\frac{a}{b}~}{c} = \frac{a}{bc},$$ and so you would enter $a$ as the numerator and $bc$ as the denominator. Try it now:
$\displaystyle\frac{~\frac{a}{b}~}{c} =$ $/$ .
