Option B is correct after applying the property of integer exponent and simplification.

<h3>What is an integer exponent?</h3>

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

We have:

$=\rm (x.x^{-3}.y^{\dfrac{1}{3}})^2$

$=\rm (x^{-2}.y^{\dfrac{1}{3}})^2\\\\=\rm (x^{-4}.y^{\dfrac{2}{3}})\\\\=\rm \dfrac{y^{\dfrac{2}{3}}}{x^{4}}\\\\$

Thus, option B is correct after applying the property of integer exponent and simplification.

Answer:

$area = area \: of \: two \: semi \: circles + area \: of \: rectangle \\ = 2( \frac{1}{2} \pi {r}^{2} ) + (l \times w) \\ = 2( \frac{1}{2} \times 3.14 \times { (\frac{18}{2}) }^{2} ) + (18 \times 4.5) \\ = 254.47 + 81 \\ = 335.5 \: {ft}^{2}$
