<em>The answer is
</em>The reason we get this answer is because when you are converting from exponential form, to radical form you always place the numerator as our constant's exponent in the radical <em>(

is called the radicand because it is located in the radical)</em> and the denominator in front of the radical, where it would be called the index.
<em>Here's what a formula would look like:</em> ![( \sqrt[n]{x} ) ^{q}=x^{ \frac{p}{q} }](https://tex.z-dn.net/?f=%28%20%5Csqrt%5Bn%5D%7Bx%7D%20%29%20%5E%7Bq%7D%3Dx%5E%7B%20%5Cfrac%7Bp%7D%7Bq%7D%20%7D%20)

Answer:
It took Pedro <em>3.81 hours</em> to reach the lake.
Step-by-step explanation:
Time taken by Mike to hike a lake = 4.5 hours
Average rate of Mike while hiking the lake = 
Formula for distance can be seen as:

Distance traveled by Mike = 
Rate of Pedro while hiking the same distance = 
Given that, Pedro also travels the same distance.
And we have to find the Time.


It took Pedro <em>3.81 hours</em> to reach the lake.
