Question

How many positive integers $n$ satisfy $\lfloor \sqrt{n} \rfloor = 5$?

Answer 1

For this case we have the following equation:
root (n) = 5
Clearing n we have:
n = 5 ^ 2
n = 25
Answer:
A positive integers n that satisfy root (n) = 5 is:
n = 25
(only one integer satisfies the equation given in the problem)
