Squaring a fraction
I have no idea how to even begin on squaring a fraction. How would I do so? Could someone walk me through squaring 39/5 (thirty-nine fifths)?

in general $\bigg( \frac xy \bigg)^a = \frac {x^a}{y^a}$

we can apply the same rule to squaring. this is just when a = 2

so, $\bigg( \frac xy \bigg)^2 = \frac {x^2}{y^2}$

can you apply that rule to this problem?
