Unable to understand the question

could you please explain the question …I am little bit confused

hello @siddhant_samal
in this problem u will be given two values n and k .
and u need to find largest value of x such that it satisfies this condition
x^k <= n

for example if n is 8 and k is 2
then we can have 2 values (1 and 2) that satiesfies the given equation
1^2 <=8 or 2^2 <=8
we will consider 2 as our answer because it is maximum among 1 and 2

sir , I have tried the question but I am not getting it …could you please share the code so that can I take reference from it

pls refer this->
