  In this article, we will explore a recent method of Alweiss \cite{key-1}
using ultrafilter technique to study monochromatic partition regular structure
of the form $\left\{ x,y,x+y,x\cdot y\right\} $ over rationals, which is
recently proved by Bowen, and Sabok in \cite{key-17}. Our methods explore that
each member of combinatorially rich ultrafilters contains these types of
configurations. Besides this, we will also prove that for any $n\in\mathbb{N},$
these sets will contain configuration of the form $\left\{ x,y,x+y,x\cdot
y^{n}\right\}$, partially proved by Xiao in \cite{key-25}.
