Answer: 
Step-by-step explanation:
 For this exercise you need to apply the Pythagorean Theorem. This is:
 
 Where "h" is the hypotenuse of the Right triangle and "l" and "m" are the legs.
 In this case, you can identify that:
 
 Knowing these values, you can substitute them into   :
:
 
 Now you must solve for "c":
 
 Evaluating, you get:
 
 To simplify the result:
 - Descompose 32 into its prime factors:
 
 - By the Product of powers property, you know that:
 
 - Make the substitution:
 
 - Finally, knowing that ![\sqrt[n]{a^n}=a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%3Da) , you get:
, you get:
