Problem Statement

Let pp be a real number and c0c\neq 0 such that c0.1<xp(1(1+x)101+(1+x)10)<c+0.1c-0.1<x^p\left(\dfrac{1-(1+x)^{10}}{1+(1+x)^{10}}\right)<c+0.1 for all (positive) real numbers xx with 0<x<101000<x<10^{-100}. (The exact value 1010010^{-100} is not important. You could replace it with any "sufficiently small number".)
Find the ordered pair (p,c)(p,c).
