1.	If f(x)=x1+(logex)(logex)⋯∞ ∀ x∈[1,3] is non-differentiable at x=k, then the value of [k2], is (where [.] denotes the greatest integer function)
Answer» If $f (x) = \frac{x}{1 + ({log}_{e} x) ({log}_{e} x) \dots \infty} \forall x \in [1, 3]$ is non-differentiable at $x = k,$ then the value of $[k^{2}],$ is (where $[.]$ denotes the greatest integer function)
