if R is the set of all real numbers,what do the Cartesian products R×R and R×R×R represent.briefly explain it
The Cartesian product R×R represents the set R×R={(x,y):x,y€R}.which represents the coordinates of all the points in two dimensional space and the carrisian product R ×R×R represents the set R ×R×R={(x,y,z):x,y,z€R}
Which represents the coordinates of all the points in three dimensional space
