જો $R$ વાસ્તવિક સંખ્યાઓનો ગણ હોય, તો $R \times R$ અને $R \times R \times R$ શું દર્શાવશે ?
Option A
Option B
Option C
Option D
Solution
The Cartesian product $R \times R$ represents the set $R \times R =\{(x, y): x, y \in R \}$ which represents the coordinates of all the points in two dimensional space and the cartesian product $R \times R \times R$ represents the set $R \times R \times R =\{(x, y, z): x, y, z \in R \}$ which represents the coordinates of all the points in three-dimensional space.
