For this case we must find an expression equivalent to:

$(x ^ {\frac {4} {3}} * x ^ {\frac {2} {3}}) ^ {\frac {1} {3}}$

By definition of power properties we have to:

$(a ^ n) ^ m = a ^ {n * m}$

So, rewriting the expression we have:

$x ^ {\frac {4} {3 * 3}} * x ^ {\frac {2} {3 * 3}} =$

$x ^ {\frac {4} {9}} * x ^ {\frac {2} {9}} =$

By definition of multiplication of powers of the same base, we put the same base and add the exponents:

$x ^ {\frac {4} {9} + \frac {2} {9}} =\\x ^ {\frac {4 + 2} {9}} =\\x ^ {\frac {6} {9}} =\\x ^ {\frac {2} {3}}$

We can use a theorem called Proportional segments in right triangles.

1. How far is library from the park?
<span>The perpendicular is the mean proportional between the segments of the hypotenuse, so:
</span> $PL= \sqrt{FL \cdot HL } = \sqrt{8 \cdot 2 } = \sqrt{16}=4 \ miles$

2. How far is the park from the football field?
<span>Each leg of the given triangle is the mean proportional between the hypotenuse and the adjacent segment, so:
</span> $PF= \sqrt{FH \cdot FL } = \sqrt{(8+2) \cdot 8 } = \sqrt{80}=4 \sqrt{5} \ miles$

Answer: A.
